Restrict P.O creatall vendor with a/c grp (Z006)

DEAR ALL

For the vendor group Z006 (Vendors-Original Manufacturers), no Accounting view nor other details related to payments, tax are being maintained. Still the users creates the P.O, subsequently executes MIGO, but during MIRO they face the error related to accounting. At this stage they realize that they have picked wrong vendor/ vendor account group. Then we have to reverse all the documents and create the same vendor with correct account group. So as to avoid all these wrong transaction execution we want to restrict the user to create the P.O for the vendor account group Z006

THANKS
