Sometimes I have a maintenance view and I need to find out if a transaction is assigned to it. It is usually not possible to find it with “where-used” list. So another approach needs to be used

Instead, Run transaction SE16 and search in table TSTCP.
Use the field PARAM where you enter the name of your view surrounded by ‘*’. Execute the search and if transaction is assigned to your maintenance view, you should see it now.

For example: If you have maintenance view V_T005 (Country Global Parameters) and want to know the transaction, go to TSTCP, look for PARAM = *V_T005* and you’ll find:
TCODE = OY01
PARAM = /*SM30 VIEWNAME=V_T005; UPDATE=X;
