Assign authorizations for SAP user according to Sales Office.

Hi Friends,

I want to set authorizations for SAP user on standard and Z,Y transaction according to their sales office.

e.g.

USER1 is belonging to PUNE region and he want to create SALES ORDER (VA01).

So he should not authorize to create SALES ORDER for other SALES OFFICE. If he try to make this he should get error message.

Same for Z report in which that user can view data of his region only.

Pleas suggest me a proper way to do that

Regard
