With every upcoming release of SAP S/4HANA, SAP brings many new features and simplifications for customers, so customers are encouraged to always upgrade to the latest release.
One important part in the planning of the upgrade, is to check the status of all deployed ABAP Add-Ons in the system. Because for every Add-On, customer must know, if it’s supported for the new release, and if/what additional package is needed for the Add-On. For Add-Ons provided by SAP or sold through SAP’s pricelist, customer can directly request the status and necessary packages from SAP. Otherwise, Add-On solutions are provided by independent 3rd party software vendors or partners, and SAP is not responsible for these Add-Ons.
In this case, it’s mandatory that the customer checks with the software vendor regarding the status of the Add-On and needed packages. Additionally, customer should check if 3rd party Add-On is certified for the target SAP S/4HANA release, as this gives confirmation, that the Add-On supports the new SAP release and the upgrade will run smoothly.
