Not displaying approvers of other plants

Hi SRM-gurus,

we have severel plants in pposa_bbp. There are of course many different users and approvers in the system.

In SRM Web-UI Shopping-transaction you can change or add an approver.

At the moment there's the situation that a user from plant A could choose an approver from plant B to approve his SC.

The standard task that's responsible for who can be chosen is maintained with the approver-roles of all plants.

Is there a way to display only A-approvers for user A and B-approvers for user B?

Thanks a lot for your help.

Best regards,

Henning
