Authorization Check in CWBQM on planer group

Hi All,

CWBQM allows authorization check with object q_rout. We use a central plant for QM master data and have  different planer groups (plko-vagrp) for the different business lines. Unfortunately q_rout doesn't include planer group.

Is there a way to add an additional authorization check? I couldn't find a suitable BadI or user exit. Any idea?

Thanks!
