This is where all the system's data resides. These are composed of the actual database and the DBMS, the "database management system". In earlier versions, the database here came from different manufacturers. For example, Microsoft SQL or Oracle. Since SAP HANA, a lot has changed for IT in this data layer. This is because the database comes from SAP itself and is automatically monitored by the system. There is more to this database layer than just the working data. Important elements such as the configuration tables and system data for control and application content are also stored here. This is the repository data used by applications.
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.
