The SAP error message AQQIS_CNTRL011 indicates that you are trying to delete tables from a join in QuickViewer (transaction code SQVI), but the system is preventing you from doing so. This typically occurs when the join has been defined in a way that makes it impossible to delete certain tables due to dependencies or constraints.
Cause: Join Dependencies: The tables you are trying to delete may have dependencies on other tables in the join. If the join is complex or if there are other tables that rely on the ones you are trying to remove, the system will not allow the deletion. Data Dictionary Constraints: There may be constraints defined in the data dictionary that prevent the deletion of certain tables from the join. Incorrect Join Type: If the join type is not appropriate for the tables involved, it may lead to issues when trying to modify the join.
Solution: Check Dependencies: Review the join definition
