Summary :
This SAP Note guides users through necessary changes for ABAP programs during an upgrade from version 4.0 to 4.5 to avoid syntax and runtime errors. Key aspects to watch include internal table handling, Open SQL updates, procedural calls, system fields, and adjustments in the ABAP compiler and runtime environment. New incompatibilities and stricter error checking in version 4.5 are detailed, along with specific instructions to ensure compatibility. Developers need to manually review ABAP code to adapt to the modified compiler behavior and runtime checks to ensure seamless functionality post-upgrade.
