We recently applied Patch 19 (SAP BW 70) to our BI systems.
Since then, we are experiencing severe performance problems, in load time, DSO activation and query execution. After testing queries in RSRT, we realized the problem is limited to the back end (Variable exit takes long time). For some reason, the problem is in Prod and QA but not in DEV, although we applied the patches to all 3 systems.
Anyone experienced that issue?
