What is SAP-BASIS?
For the SAP basis and its employees, the change in self-understanding results in an attractive, responsible and demanding working environment. Technological diversity can be controlled and kept to the minimum necessary.

A BW system often plays a very central role in larger companies. Here the data from the various connected source systems are analysed and reported centrally. A previous customer of mine had a BW system, to which a total of over 20 other SAPP production systems were connected. With such a large and mostly living system landscape, it is normal that individual systems are dismantled from time to time. However, especially with large SAP landscapes, there are strict regulations regarding the permissions of technical RFC users. For this reason, the simple "right-click —> delete" of a source system in RSA1 will often not lead to the target, but rather to a failed permission check. With this blog post, I'll show you a workaround on how to clean a source system from a BW system using the RSAR_LOGICAL_SYSTEM_DELETE and RSAP_BIW_DISCONNECT function blocks.
Virtualization of your entire SAP system landscape (some companies additionally operate an SAP HCM system, for example, which also needs to be virtualized)

Trust is good, control is better In order to avoid employees being entitled beyond your area of competence, user data and permissions must be continuously adjusted to the current requirements.
