Common Breakage Patterns in S/4HANA Custom ABAP Code
This technical analysis highlights the significant challenges engineers face during brownfield migrations to SAP S/4HANA, specifically focusing on the failure of custom ABAP code. Unlike standard software upgrades, the transition to S/4HANA involves a fundamental architectural shift characterized by a simplified data model and revised underlying logic. Consequently, many traditional SAP ECC tables and transactions are either removed or function differently, causing legacy Z-programs that previously operated correctly to either crash with short-dumps or generate inaccurate results. The article serves as a guide for identifying these common breakage patterns, emphasizing that the incompatibility stems from the structural differences between the older ECC environment and the new S/4HANA framework. By understanding these specific technical hurdles, organizations can better prepare for migration projects, ensuring that custom developments are reviewed and adjusted to align with the new system requirements. This insight is crucial for IT teams aiming to prevent operational disruptions and maintain data integrity during large-scale enterprise resource planning conversions.
