Summary :
In the scenario where variable inputs are pre-defined (e.g., in workbooks or views), selecting variable values via F4 can trigger Message 789(DB), indicating a query execution error and an inability to modify selection due to non-assignable LOW values in hidden variables. The root cause is identified as a bug in the RRS1 function group. To resolve, clients should implement Support Package 25 for BW2.0B or Support Package 17 for BW2.1C. Relevant details are in SAP Note 0456554 for BW2.0B and SAP Note 0456568 for BW2.1C, with further guidance found in Note 110934.
