In case you would like to check on the relevance of simplification items only, or check on the system consistency before conversion, SAP has introduced a Simplification Item Check (SI-Check) with SAP S/4HANA 1709.
The Simplification Item Check consists of a report /SDF/RC_START_CHECK and a related check framework which you shall run
- on your SAP ERP system as preparation for a system conversion to SAP S/4HANA.
- on your SAP S/4HANA system as preparation for a release upgrade to a higher SAP S/4HANA release.
The SI-Check is completely new re-designed based on the content in the Simplification Item Catalog and performs the same checks the Software Update Manager SUM will process in front of the real system conversion. The SI-Check can be executed in addition to the SAP Readiness Check for SAP S/4HANA.
The Simplification Item Check serves two purposes:
- Relevance check: Determine which Simplification Items are relevant for the specific system in which you are running the Simplification Item Check. This shall help you to assess the functional and technical impact of the system conversion on your system.
- Consistency check: During the conversion process your system will be migrated to the new data structures and new processes. The conversion routines rely on consistent data in the system in order for this to happen automatically. If the Simplification Item Check identifies data inconsistencies or missing mandatory preparation activities which could cause the system conversion to fail, it will make you aware of these issues so you can correct or exempt them before the actual system conversion starts.
The SI-Check is delivered with SAP Notes 2399707 and 2418800. SAP Note 2399707 includes the new check report /SDF/RC_START_CHECK; SAP Note 2418800 delivers the check classes via transport-based correction instructions (TCI). The check report calls the check classes. Check both SAP notes for more information.
