This event occurs after the selection conditions are read from the ABAP Dictionary and possibly entered by the user in a selection screen.
You can put further view cluster object selection conditions in the internal table " DBA_SELLIST ".
You must check whether any selection conditions which you enter are also valid for dependent objects. If so, you must also maintain the selection conditions in the internal tables DBA_SELLIST and
DPL_SELLIST for the dependent objects.

You can cancel view cluster maintenance by setting VCL_ACTION = SPACE .
