Add the powerlist ZPOWL into active Queries

Dear Experts,

how can a ZPOWL (Customer POWL) can be integrated into Active Queries in SRM generally.

I have followed all described steps. But in my case I need to implement the powl query within "Active Queries" as above shown

and not in a Z WebDynpro Component

POWL in Webdynpro ABAP - Team ABAP
