MRP is generating Purchase Requisition with account assignment "M"

[Former Member]

Hi All,

We have Process of special sales order with "TAB" item category and PR will be generated as soon as Sales order is saved/released. Sometimes we have PR which is generated from MRP for same sales order which is already having PR. As it is special order with TAB item category, it will have Account assignment M. So now we have 2 PRs for same Sales order and buyer can create 2 Purchase order for one Sales order and that is causing issue.

\

What is causing MRP to generate PR for material which it is not supposed to generate. We have MRP type PD purposefully. Is there any other reason as when you see MD04 after sales order creation, we always see PR so MRP should not generate another PR.

Any pointers will be rewarded.

Thanks for help in advance.

Regards,

Tt

Hello

You should change the requirement class/type customizing and make sure that it is not transferring requirements for MRP. Check in the customizing transaction OVZG / OVZH and make sure that the field NOMRP is set properly.
