Cost Center Authorization in MB21

Dear Sir,

We are unable to restrict the user to create reservation for one plant and choosing the cost center for the same plant. He may choose cost center of different plant for movement type 201 in T.Code MB21. The same is also happening in case of reservation through 221 and choosing WBS.

We want to know how can we restrict the same. We have checked it through our BASIS Team.

Regards

Mudit Gupta
