Troubleshooting and support

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.

The result table USERTCODE contains the transaction codes of the SAP users. Afterwards you simply have to output the complete list via "Object > Output complete list". Then save the list via "System > List > Save > Local file". The column Account contains the SAP user. This way you can see the used transactions grouped by SAP user.

All profiles ending on "_ALL" are considered critical, as they usually grant all permissions relevant to a subset in the system, application, or module.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
