Conversion to SAP S/4HANA using SUM: ABAP Systems on UNIX and Linux

Adjusting Customer Developments

Context

The programs and applications that you have written, which run without errors on the source release, may contain syntax or runtime errors after the update. These may be caused by additional developments of the ABAP Workbench, changes to the ABAP syntax, or stronger syntax checks when you update from one release of SAP Basis, SAP Web AS, or SAP NetWeaver AS to the next one. You can solve these problems by adjusting your programs to the new version of the ABAP Workbench.

We also recommend to check the customer developments, which will be replaced by SAP standard during the update, if they are still necessary.

Procedure

For information about adjusting customer developments (recommendations for adjustments and instructions), see the composite SAP Note 2388441 Information published on SAP site. It contains an overview of all SAP Notes for changes that must be kept in mind in the case of an ABAP release change.
