How Zengines Mainframe Data Lineage Solves Critical Data Element Challenges for Financial Institutions

May 9, 2025
Greg Shoup

In today's increasingly regulated financial landscape, banks and financial institutions face mounting pressure to ensure complete visibility and traceability of their Critical Data Elements (CDEs). While regulatory frameworks like BCBS 239, CDD, and CIP establish clear requirements for data governance, many organizations struggle with implementation, particularly when critical information resides within decades-old mainframe systems.

These legacy environments have become the Achilles' heel of compliance efforts, with opaque data flows and hard-to-decipher COBOL code creating significant blind spots. Zengines Mainframe Data Lineage product offers a revolutionary solution to this challenge, providing unparalleled visibility into "black box" systems and transforming regulatory compliance from a time-consuming burden into an efficient, streamlined process.

The Regulatory Challenge of Critical Data Elements

For banks and financial services firms, managing Critical Data Elements (CDEs) is no longer optional - it's a fundamental regulatory requirement with significant implications for compliance, risk management, and operational integrity. Regulations like BCBS 239, the Customer Due Diligence (CDD) Rule, and the Customer Identification Program (CIP) mandate that financial institutions not only identify their critical data but also understand its origins, transformations, and dependencies across all systems.

However, for institutions with legacy mainframe systems, this presents a unique challenge. These "black box" environments, often powered by decades-old COBOL code spread across thousands of modules, make tracing data lineage a time-consuming and error-prone process. Without the right tools, financial institutions face substantial risks, including regulatory penalties, audit failures, and compromised decision-making.

"Financial institutions today are trapped between regulatory demands for data transparency and legacy systems that were never designed with this level of visibility in mind. At Zengines, we've created Mainframe Data Lineage to bridge this gap, turning black box mainframes into transparent, auditable systems that satisfy even the most stringent CDE requirements." - Caitlyn Truong, CEO, Zengines

The Hidden Compliance Challenge in Legacy Systems

Many financial institutions operate with legacy mainframe technology that can contain up to 80,000 different COBOL modules, each potentially containing thousands of lines of code. This complexity creates several critical challenges for CDE compliance:

  1. Opacity of Data Origins: When regulators ask "Where did this value come from?", companies struggle to provide clear, documented answers from within mainframe systems.
  2. Calculation Verification: Understanding how critical values like interest accruals, risk assessments, or customer identification data are calculated becomes nearly impossible without specialized tools.
  3. Conditional Logic Tracing: Determining why specific data paths were followed or how specific business rules are implemented requires manually tracing through complex code branches.
  4. Resource Scarcity: Limited availability of mainframe or COBOL experts makes compliance activities dependent on a shrinking pool of specialized talent.
  5. Documentation Gaps: Years of system changes with inconsistent documentation practices have left critical knowledge gaps about data elements and their transformations.

"The challenge with mainframe environments isn't that the data isn't there—it's that it's buried in thousands of COBOL modules and complex code paths that would take months to manually trace. Zengines automates this process, reducing what would be weeks of research into minutes of interactive exploration." - Caitlyn Truong, CEO, Zengines

Introducing Zengines Mainframe Data Lineage

Zengines Mainframe Data Lineage product is purpose-built to solve compliance challenges like these by bringing transparency to legacy systems. By automatically analyzing and visualizing mainframe data flows, it enables financial institutions to meet regulatory requirements without the traditional manual effort.

How Zengines Transforms CDE Compliance

1. Automated Data Traceability

Zengines ingests COBOL modules, JCL code, SQL, and other mainframe components to automatically map relationships between data elements across your entire mainframe environment. This comprehensive approach ensures that no critical data element remains untraced.

2. Visual Data Lineage

Instead of manually tracing through thousands of lines of code, Zengines provides interactive visualizations that instantly show:

  • Where data originates
  • How it transforms through calculations
  • Which conditions affect its processing
  • Where it ultimately flows

This visualization capability is particularly valuable during regulatory examinations, allowing institutions to demonstrate compliance with confidence and clarity.

3. Calculation Logic Transparency

For BCBS 239 compliance, institutions must understand and validate calculation methodologies for risk data aggregation. Zengines automatically extracts and presents calculation logic in human-readable format, making it simple to verify that risk metrics are computed correctly.

4. Branch Condition Analysis

When regulators question why certain customer records received specific treatment (critical for CDD and CIP compliance), Zengines can immediately identify the conditional logic that determined the data path, showing exactly which business rules were applied and why.

5. Comprehensive Module Statistics

Zengines provides detailed metrics about your mainframe environment, helping compliance teams understand the scope and complexity of systems containing critical data elements.

"When regulators ask where a critical value came from or how it was calculated, financial institutions shouldn't have to launch a massive investigation. With Zengines Mainframe Data Lineage, they can answer these questions confidently and immediately, transforming their compliance posture from reactive to proactive." - Caitlyn Truong, CEO, Zengines

Real-World Impact: Accelerating Compliance Activities

Financial institutions using Zengines Mainframe Data Lineage have experienced transformative results in their regulatory compliance activities:

  • 90% Reduction in Audit Response Time: Questions about data calculations that previously took weeks or months to research can now be answered in minutes.
  • Enhanced Confidence in Regulatory Reporting: With the ability to see, follow, and explain data origins and transformations, institutions can ensure the accuracy of regulatory reports.
  • Reduced Dependency on Specialized Resources: Business analysts can now answer many compliance questions without requiring mainframe expertise.
  • Improved Risk Management: Comprehensive visibility into how critical risk metrics are calculated enables better oversight and governance.
  • Future-Proofed Compliance: As regulations evolve, having comprehensive data lineage documentation ensures adaptability to new requirements.

Beyond Compliance: Strategic Benefits

While regulatory compliance drives initial adoption, financial institutions discover additional strategic benefits from implementing Zengines Mainframe Data Lineage:

  1. System Modernization Support: The detailed understanding of data flows facilitates safer, faster and more accurate modernization from legacy systems - this may include requirements gathering, new development, data migration, data testing, reconciliation, etc.
  2. Operational Efficiency: Rapid identification of data dependencies reduces development time for system changes.
  3. Risk Reduction: Comprehensive visibility into mainframe operations reduces operational risk associated with mainframe management and changes.
  4. Knowledge Preservation: As mainframe experts retire, their implicit knowledge becomes explicitly documented through Zengines.

"What we've discovered working with financial services firms is that CDE compliance isn't just about satisfying regulators—it's about fundamentally understanding your own critical data. Our Mainframe Data Lineage solution doesn't just help banks pass audits; it gives them unprecedented insight into their own operations." - Caitlyn Truong, CEO, Zengines

The 2008 financial crisis exposed a shocking truth: major banks couldn't accurately report their own risk exposures in real-time.

When Lehman Brothers collapsed, regulators discovered that institutions didn't know their actual exposure to toxic assets -- not because they were hiding it, but because they genuinely couldn't aggregate their own data fast enough.

Fifteen years and billions in compliance spending later, only 2 out of 31 Global Systemically Important Banks fully comply with BCBS-239 -- the regulation designed to prevent this exact problem.

The bottleneck? Data lineage.

Who Must Comply and When

BCBS-239 applies from January 1, 2016 for Global Systemically Important Banks (G-SIBs) and is recommended by national supervisors for Domestic Systemically Important Banks (D-SIBs) three years after their designation. In practice, this means hundreds of banks worldwide are now expected to comply.

Unlike regulations with fixed annual filing deadlines, BCBS-239 is an ongoing compliance requirement. Supervisors can test a bank's compliance with occasional requests on selected risk issues with short deadlines, gauging a bank's capacity to aggregate risk data rapidly and produce risk reports.

Think of it as a fire drill that can happen at any moment -- and with increasingly serious consequences for failure.

The Sobering Statistics

More than a decade after publication and eight years past the compliance deadline, the results are dismal. Only 2 out of 31 assessed Global Systemically Important Banks fully comply with all principles, and no single principle has been fully implemented by all banks.

Even more troubling, the compliance level across all principles barely improved from an average of 3.14 in 2019 to 3.17 in 2022 on a scale of 1 ("non-compliant") to 4 ("fully compliant"). At this rate of improvement, full compliance is decades away.

What Happens If Your Bank Fails BCBS-239 Compliance?

The consequences are escalating. The ECB guide explicitly mentions:

  • Enforcement actions against the institution
  • Capital add-ons to compensate for data risk
  • Removal of responsible executives who fail to drive compliance
  • Operational restrictions on new business lines or acquisitions

The Basel Committee makes it clear that banks' progress towards BCBS 239 compliance in recent years has not been satisfactory and that increased measures on the part of the supervisory authorities are to be expected to accelerate implementation.

What Banks Are Doing (And Why It's Not Enough)

Most banks have responded to BCBS-239 with predictable tactics:

  • Governance restructuring: Creating Chief Data Officer roles and data governance committees
  • Policy documentation: Writing comprehensive data management policies and frameworks
  • Technology investments: Purchasing disparate tools like data catalogs, metadata management tools, and master data management platforms
  • Remediation programs: Launching multi-year, multi-million dollar compliance initiatives

These tactics, as positive steps forward, are necessary but not sufficient to meeting compliance. In other words, they're checking boxes without fundamentally solving the problem.

The issue? Banks are treating BCBS-239 like a project with an end date, when it's actually an operational capability that must be demonstrated continuously.

The Data Lineage Bottleneck

Among the 14 principles, one capability has emerged as the make-or-break factor for compliance: data lineage.

Data lineage has been identified as one of the key challenges that banks have faced in aligning to the BCBS-239 principles, as it is one of the more time consuming and resource intensive activities demanded by the regulation.

Why Data Lineage Is Different

Data lineage -- the ability to trace data from its original source through every transformation to its final destination -- sits at the intersection of virtually every BCBS-239 principle. The European Central Bank refers to data lineage as "a minimum requirement of data governance" in the latest BCBS 239 recommendations.

Here's why lineage is uniquely difficult:

It's invisible until you need it.
Unlike a data governance policy you can show an auditor or a data quality dashboard you can pull up, lineage is about proving flows, transformations, and dependencies that exist across dozens or hundreds of systems. You can't fake it in a PowerPoint.

It crosses organizational and system boundaries.
Complete lineage requires cooperation between IT, risk, finance, operations, and business units -- each with their own priorities, systems, and definitions. Further, data hand-off occurs in and between systems, databases and files, which adds to the complexity of connecting what happens at each hand-off.  Regulators are increasingly requiring detailed traceability of reported information, which can only be achieved through lineage across organizations and systems.

It must be current and complete.
The ECB requires "complete and up-to-date data lineages on data attribute level (starting from data capture and including extraction, transformation and loading) for the risk indicators, and their critical data elements." A lineage document from six months ago is worthless if your systems have changed.

It must work under pressure.
Supervisors increasingly require institutions to demonstrate the effectiveness of their data frameworks through on-site inspections and fire drills, with data lineage providing the audit trail necessary for these reviews. When a regulator asks "prove this number came from where you say it came from," you have hours -- not days -- to respond.

The Eight Principles That Demand Data Lineage Proof

While 11 of the 14 principles benefit from good data lineage, regulatory guidance makes it explicitly mandatory for eight:

  • Principle 2 (Data Architecture): Demonstrate integrated data architecture through documented lineage flows
  • Principle 3 (Accuracy & Integrity): Prove data accuracy by showing traceable lineage from source to report
  • Principle 4 (Completeness): Demonstrate comprehensive risk coverage through lineage mapping
  • Principle 6 (Adaptability): Respond to ad-hoc requests using lineage to quickly identify relevant data
  • Principle 7 (Report Accuracy): Validate report numbers through documented lineage and audit trails
  • Principles 12-14 (Supervisory Review): Provide lineage evidence during audits and fire drills

The Technology Gap: Why Traditional Tools Fall Short

Most banks have invested heavily in data catalogs, metadata management platforms, and governance frameworks. Yet they still can't produce lineage evidence under audit conditions. Why?

Traditional approaches have three fatal flaws:

1. Manual Documentation

Excel-based lineage documentation becomes outdated within weeks as systems change. By the time you finish documenting one data flow, three others have been modified. Manual approaches simply can't keep pace with modern banking environments.

2. Point Solutions that only support newer applications

Modern data lineage tools can map cloud warehouses and APIs, but they hit a wall when they encounter legacy mainframe systems. They can't parse COBOL code, decode JCL job schedulers, or trace data through decades-old custom applications -- exactly where banks' most critical risk calculations often live.

3. Incomplete Coverage

Lineage that stops at the data warehouse is fundamentally incomplete under BCBS-239's end-to-end data lineage requirements. Regulators want to see the complete path -- from original source system through every transformation, including hard-coded business logic in legacy applications, to the final risk report. Most tools miss 40-70% of the actual transformation logic.

How AI-Powered Data Lineage Changes the Game

This is where AI-powered solutions like Zengines fundamentally differ from traditional approaches.

Instead of manually documenting lineage, Zengines can automatically and comprehensively:

  • Parse legacy mainframe code (COBOL, RPG, Focus, etc) to extract data flows and transformation logic
  • Trace calculations backward from any report field to ultimate source systems
  • Document relationships between tables, fields, programs, files and job schedulers
  • Generate audit-ready evidence in minutes instead of months
  • Maintain relevancy and currency through lineage updates as code changes

Solving the "Black Box" Problem

For many banks, the biggest lineage gap isn't in modern systems -- it's in legacy mainframes where critical risk calculations were encoded 20-60 years ago by developers who have long since retired. These systems are literal "black boxes": they produce numbers, but no one can explain how.

Zengines' Mainframe Data Lineage capability specifically addresses this challenge by:

  • Parsing COBOL and RPG modules to expose calculation logic and data dependencies
  • Tracing variables across millions of lines of legacy code
  • Identifying hard-coded values, conditional logic, and branching statements
  • Visualizing data flows across interconnected mainframe programs and external files
  • Extracting "requirements" that were never formally documented but are embedded in code

This capability is essential for banks that need to prove how legacy calculations work -- whether for regulatory compliance, system modernization, or simply understanding their own risk models.

Assessment: Can Your Bank Prove Compliance Right Now?

The critical question isn't "Do we have data lineage?" It's "Can we prove compliance through data lineage right now, under audit conditions, with short notice?"

Most banks would answer: "Well, sort of..."

That's not good enough anymore.

We've translated ECB supervisory expectations into a practical, principle-by-principle checklist. This isn't about aspirational capabilities or future roadmaps -- it's about what you can demonstrate today, under audit conditions, with short notice.

The Bottom Line

The bottleneck to full BCBS-239 compliance is clear: data lineage.

Traditional approaches -- manual documentation, point solutions, incomplete coverage -- can't solve this problem fast enough. The compliance deadline was 2016. Enforcement is escalating. Fire drills are becoming more frequent and demanding.

Banks that solve the lineage challenge with AI-powered automation will demonstrate compliance in hours instead of months. Those that don't will continue struggling with the same gaps, facing increasing regulatory pressure, and risking enforcement actions.

The technology to solve this exists today. The question is: how long can your bank afford to wait?

BOSTON, MA – October 29, 2025 – Zengines, the AI-powered data migration and data lineage platform, announces expanded support for RPG (Report Program Generator) language in its Data Lineage product. Organizations running IBM i (AS/400) systems can now rapidly analyze legacy RPG code alongside COBOL, dramatically accelerating modernization initiatives while reducing dependency on scarce programming expertise.

Breaking Through the RPG "Black Box"

Many enterprises still rely on mission-critical applications written in RPG decades ago, creating what Zengines calls the "black box" problem – legacy technology where business logic, data flows, and requirements are locked away in legacy code with little to no documentation. As companies undertake digital transformation and cloud migration initiatives, understanding these legacy systems has become a critical bottleneck.

The challenge with RPG is particularly acute. While COBOL's descriptive, English-like syntax makes it easier to "read," RPG's fixed-format column specifications and cryptic operation codes require developers to decode what goes in which column while tracing through numbered indicators to follow the logic. This complexity, combined with a shrinking pool of RPG expertise, makes understanding these systems even more critical—and difficult—than their COBOL counterparts.

"The majority of our enterprise customers are running legacy technology across multiple platforms – both mainframe COBOL environments and IBM i systems with RPG code," said Caitlyn Truong, CEO of Zengines. "By expanding our support to include RPG alongside COBOL, we can now address the full spectrum of legacy code challenges these organizations face. This means our customers can leverage a single AI-powered platform to comprehensively analyze, understand and modernize their legacy technology estate, rather than cobbling together multiple point solutions or relying on increasingly scarce programming expertise across different languages and systems."

Minutes, Not Months: AI-Powered Legacy Code Analysis

The enhanced Zengines Data Lineage platform automatically ingests RPG code, job schedulers, and related artifacts to deliver:

  • Interactive data lineage visualization – Graphical representation of data paths, sources, and hard-coded values
  • Comprehensive code intelligence – Relationships between modules, tables, fields, variables, and files
  • Business logic extraction – Calculation logic, branching conditions, and transformation rules
  • Actionable insights – Tables and fields inventory, profiling, and impact analysis

This capability is critical for organizations navigating system replacements, M&A integrations, compliance initiatives, and technology modernization programs where understanding legacy RPG logic is essential for de-risking implementations.

Real-World Impact: From Guesswork to Precision

Managing and modernizing legacy systems break down when teams lack complete understanding of existing logic. Migrations stall when teams cannot achieve functional coverage or resolve test failures. When validating new systems against legacy outputs, discrepancies inevitably emerge – but without understanding why the old system produces specific results, teams cannot effectively test, replicate, or improve functionality.

"Our customers use Zengines to reverse-engineer business requirements from legacy code," added Truong. "When a new system returns a different result for an interest calculation compared to that of  the 40-year-old RPG program, teams need to understand the original logic to make informed decisions about what to preserve and what to update. That's the power of shining a light into the black box."

Immediate Availability

RPG parsing capability is now available on Zengines Data Lineage platform. Organizations can analyze both COBOL and RPG codebases within a single integrated platform.

IBM's RPG (Report Program Generator) began in 1959 with a simple mission: generate business reports quickly and efficiently. What started as RPG I evolved through multiple generations - RPG II, RPG III, RPG LE, and RPG IV - each adding capabilities that transformed it from a simple report tool into a full-featured business programming language. Today, RPG powers critical business applications across countless AS/400, iSeries, and IBM i systems. Yet for modern developers, understanding RPG's unique approach and legacy codebase presents distinct challenges that make comprehensive data lineage essential.

The Strengths That Made RPG Indispensable

Built-in Program Cycle: RPG's fixed-logic cycle automatically handled file operations, making database processing incredibly efficient. The cycle read records, processed them, and wrote output with minimal programmer intervention - a major strength that processed data sequentially, making it ideal for report generation and business data handling.

Native Database Integration: RPG was designed specifically for IBM's database systems, providing direct interaction with database files and making it ideal for transactional systems where fast and reliable data processing is essential. It offered native access to DB2/400 and its predecessors, with automatic record locking, journaling, and data integrity features.

Rapid Business Application Development: For its intended purpose - business reports and data processing - RPG was remarkably fast to code. The fixed-format specifications (H, F, D, C specs) provided a structured framework that enforced consistency and simplified application creation.

Exceptional Performance and Scalability: RPG applications typically ran with exceptional efficiency on IBM hardware, processing massive datasets with minimal resource consumption. RPG programming language has the ability to handle large volumes of data efficiently.

Evolutionary Compatibility: The language's evolution path meant that RPG II code could often run unchanged on modern IBM i systems - a testament to IBM's commitment to backward compatibility that spans over 50 years.

The Variations That Created Complexity

RPG II (Late 1960s): The classic fixed-format version with its distinctive column-specific coding rules and built-in program logic cycle, used on System/3, System/32, System/34, and System/36.

RPG III (1978): Added subroutines, improved file handling, and more flexible data structures while maintaining the core cycle approach. Introduced with System/38, later rebranded as "RPG/400" on AS/400.

RPG LE - Limited Edition (1995): A simplified version of RPG IV designed for smaller systems, notably including a free compiler to improve accessibility.

RPG IV/ILE RPG (1994): The major evolution that introduced modular programming with procedures, prototypes, and the ability to create service programs within the Integrated Language Environment - finally bringing modern programming concepts to RPG.

Free-Format RPG (2013): Added within RPG IV, this broke away from the rigid column requirements while maintaining backward compatibility, allowing developers to write code similar to modern languages.

The Weaknesses That Challenge Today's Developers

Steep Learning Curve: RPG's fixed-logic cycle and column-specific formatting are unlike any modern programming language. New developers must understand both the language syntax and the underlying program cycle concept, which can be particularly challenging.

Limited Object-Oriented Capabilities: Even modern RPG versions lack full object-oriented programming capabilities, making it difficult to apply contemporary design patterns and architectural approaches.

Cryptic Operation Codes: Traditional RPG used operation codes like "CHAIN," "SETLL," and "READE" with rigid column requirements that aren't intuitive to developers trained in modern, free-format languages.

Complex Maintenance Due to Evolution: The evolution from RPG II (late 1960s) through RPG III (1978) to RPG IV/ILE RPG (1994) and finally free-format coding (2013) created hybrid codebases mixing multiple RPG styles across nearly 50 years of development, making maintenance and understanding complex for teams working across different generations of the language.

Proprietary IBM-Only Ecosystem: Unlike standardized languages, RPG has always been IBM's proprietary language, creating vendor lock-in and concentrating expertise among IBM specialists rather than fostering broader community development.

The Legacy Code Challenge: Why RPG Is Particularly Difficult Today

RPG presents unique challenges that go beyond typical legacy system issues, rooted in decades of development practices:

  • Multiple Format Styles in Single Systems: A single system might contain RPG II fixed-format code (1960s-70s), RPG III subroutines (1978+), RPG LE simplified code (1995+), and RPG IV/ILE procedures with free-format sections (1994+) - all working together but following different conventions and programming paradigms developed across 50+ years, making unified understanding extremely challenging.
  • Embedded Business Logic: RPG's tight integration with IBM databases means business rules are often embedded directly in database access operations and the program cycle itself, making them hard to identify, extract, and document independently.
  • Minimal Documentation Culture: The RPG community traditionally relied on the language's self-documenting nature and the assumption that the program cycle made logic obvious, but this assumption breaks down when dealing with complex business logic or when original developers are no longer available.
  • Proprietary Ecosystem Isolation: RPG development was largely isolated within IBM midrange systems, creating knowledge silos. Unlike languages with broader communities and extensive online resources, RPG expertise became concentrated among IBM specialists, limiting knowledge transfer.
  • External File Dependencies: RPG applications often depend on externally described files (DDS) where data structure definitions live outside the program code, making data relationships and dependencies difficult to trace without specialized tools.

Making Sense of RPG Complexity: The Data Lineage Solution

Given these unique challenges - multiple format styles, embedded business logic, and lost institutional knowledge - how do modern teams gain control over their RPG systems without risking business disruption? The answer lies in understanding what your systems actually do before attempting to change them.

Modern data lineage tools provide exactly this understanding by:

  • Analyzing all RPG variants within a single system, providing unified visibility across decades of development spanning RPG II through modern free-format code.
  • Mapping database relationships from database fields through program logic to output destinations, since RPG applications are inherently database-centric.
  • Discovering business rules by analyzing how data transforms as it moves through RPG programs, helping teams reverse-engineer undocumented logic.
  • Assessing impact before making changes, identifying all downstream dependencies - crucial given RPG's tight integration with business processes.
  • Planning modernization by understanding data flows, helping teams make informed decisions about which RPG components to modernize, replace, or retain.

The Bottom Line

RPG systems represent decades of business logic investment that often process a company's most critical transactions. While the language may seem archaic to modern eyes, the business logic it contains is frequently irreplaceable. Success in managing RPG systems requires treating them not as outdated code, but as repositories of critical business knowledge that need proper mapping and understanding.

Data lineage tools bridge the gap between RPG's unique characteristics and modern development practices, providing the visibility needed to safely maintain, enhance, plan modernization initiatives, extract business rules, and ensure data integrity during system changes. They make these valuable systems maintainable and evolutionary rather than simply survivable.
