How to migrate financial data seamlessly in complex SAP M&A scenarios

In today's dynamic business environment, Mergers and Acquisitions (M&A) and re-organisations are common occurrences that necessitate the seamless migration of financial data between SAP systems. Ensuring the integrity and auditability of this crucial information is important, and the only way to achieve this is through the meticulous management of journal entries. This approach guarantees compliance with regulatory standards, and maintains the accuracy of financial records, so financial data cannot be altered through technical means alone.

M&A, divestiture and upgrade scenarios: complexity of financial data migration

As early as 2020, we were delving further into the complex M&A logical separation space – the area SAP would call SLO (System Landscape Optimisation) or DMLT (Data Management and Landscape Transformation). We developed a transformation engine, and started to really flex our muscles as a company highly differentiated by mature software that could do extensive in-place transformations, as well as selective and highly complex point-to-point ETL (Extract, Transform, Load) operations for divestitures and selective migrations.

When organisations undergo M&A activities, divestitures, S/4HANA Greenfield and Hybrid Upgrades, or internal re-organisations, the underlying IT infrastructure – particularly the financial systems – needs to adapt rapidly. This often involves:

• Moving large amounts of data
  High transactional volumes mean a massive amount of data needs to be moved and reconciled accurately. This is not just about copying data; it's about transforming it to fit new organisational structures and reporting requirements. We realised that high volume FI postings and asset migrations had to be executed functionally alongside what was otherwise mostly a giant technical ETL process, with a functional data map powered by our large proprietary data modelling software.
• Maintaining data integrity and auditability
  Maintaining the integrity and auditability of financial records throughout the migration process is paramount. Any discrepancies can lead to significant compliance issues, financial reporting errors and loss of trust.
• Solving complex system landscape challenges
  Complex SAP landscapes, especially those involving SAP S/4HANA, require sophisticated approaches to ensure that all modules and integrated systems continue to function seamlessly post-migration.
• Ensuring business continuity
  Minimising downtime during the migration process is critical to ensure business continuity. Delays can result in lost revenue and operational disruptions.
• Alignment with new organisational structure
  Aligning the technical migration with the new organizational structure, including profit centres, cost centres and master data is a complex task. This alignment requires meticulous planning and execution.

Principles for successful data migration in complex scenarios

Successful financial data migration in complex M&A, logical separation and upgrade scenarios hinges on several key principles:

• Strategic planning and scope definition: Before any technical work begins, a clear understanding of the project scope, objectives, and desired outcomes is essential. This includes defining what data needs to be moved, what transformations are required, and the target system's configuration.
• Robust ETL strategy: A well-defined ETL strategy is crucial for handling large volumes of data. This involves:
  • Extraction: Efficiently extracting data from source systems without impacting live operations.
  • Transformation: Applying necessary business rules and mapping to conform to the target system's structure. This often includes currency conversions, remapping of GL accounts, and adjustments for new organizational entities (e.g., profit centres, cost centres).
  • Loading: Securely loading transformed data into the target system while maintaining data integrity.
• Minimising downtime: Employing strategies that minimise downtime – such as phased migrations, incremental data loads, and thorough testing in a non-production environment – is critical for business continuity.
• Master Data Management (MDM): Effective master data management is fundamental. This includes harmonising and consolidating master data (e.g., customer, vendor, material, and financial master data) across the merged or separated entities. This is particularly important for profit centre reorganizations and master data reclassifications.
• Comprehensive testing: Rigorous testing, including unit testing, integration testing, and user acceptance testing (UAT), is essential to validate the accuracy and completeness of the migrated data and the functionality of the new system landscape. This should cover financial postings, reporting, and integration with other business processes.
• Audit trail and compliance: Ensuring a comprehensive audit trail of all migration activities is crucial for compliance and regulatory requirements. This includes detailed logging of all transactions and transformations.

The importance of journal entries in balance sheet migrations

Balance sheet migrations involve transferring open items and balances from one SAP system or company to another. This process must be handled with journal entries to ensure that every transaction is recorded accurately and transparently. Journal entries provide a clear audit trail, which is essential for meeting regulatory requirements and ensuring the integrity of financial data. Without this level of detail, businesses risk compromising the accuracy of their financial statements and facing potential compliance issues.

PRISM Posting Engine: new balance sheet migration tool for SAP systems

Following our considerable experience in a wide variety of projects, we have now added the PRISM Posting Engine to our PRISM solutions.

PRISM is our software-enabled Selective Data Transition (SDT) service for S/4HANA and Payroll. It is underpinned by a large selection of software and automation tools to speed up and de-risk transformation projects by providing an end-to-end automation framework for both technical data transition and finance related data postings.

In the context of M&A operations, the PRISM Posting Engine further strengthens our unique capabilities to remove the need for close-and-rekey operations for clients when we're helping them logically separate as part of M&A activities (such as Plant Reallocations and Company Code Splits/Mergers), or simply reorganising internally (such as Profit Centre Reorganisations or Master Data Reunifications).

In a nutshell, PRISM Posting Engine automates the selection, mapping, and processing of journal entries, facilitating the migration of the Balance Sheet. While it does not manage inventory migration on its own (although can be used as part of a stock migration solution), its capabilities in handling other critical financial data make it an invaluable asset for any migration project.

PRISM Posting Engine: benefits

Benefits of using the PRISM Posting Engine and our financial transformation consultants include:

• Reduced implementation time: The automation capabilities of our tool significantly reduce the time required to implement migration solutions, allowing for faster project completion.
• Better performance: Enhanced performance ensures that migrations are executed efficiently, minimising downtime and operational disruptions.
• High data quality: Our tool ensures high data quality by accurately mapping and processing journal entries, reducing the risk of errors and discrepancies.
• Efficient error handling: Advanced error handling mechanisms detect and resolve issues promptly, ensuring smooth and uninterrupted migrations.
• Traceability and auditability: The detailed audit trails provided by journal entries ensure complete traceability and auditability, meeting regulatory standards and providing peace of mind
• Minimised manual intervention: By automating journal entry processing and validation, the PRISM Posting Engine significantly reduces reliance on manual tasks, thereby lowering the risk of human error and ensuring more consistent and reliable financial data migrations.

With our new PRISM Posting Engine and the support of our expert financial consultants, you can confidently navigate the complexities of financial data migrations in SAP systems.
