Pegging Purchase Reqs to Production Orders to Group

[sam_wardill]

We would like to group Purchase Reqs by Production Order so that we create a one to one relationship between Purchase Order & Production Order.

Generally we convert Purchase Reqs to Purchase Orders using ME21N. If we run MRP lot for lot is there any way to peg to Production Order to the PO such that you could see the origin of a Purchase Req in ME21N?

Failing that, can anyone think of another way to peg Purchase Reqs to Production Orders such that a buyer could convert Purchase Reqs to Purchase Orders maintaining a one to one relationship between Purchase Orders and Production Order?

Thanks fesalbod . We do want to peg the purchase order of the components to the production order number. The solution you describe seems manual (which is something I was hoping to avoid) but I think we could ask IT to write a programme to automate it. I will look into this.

Hi Sam, based on my understanding you want to peg the purchase order of the components to the production order number. Please let me know if this is correct. If this case is what you are trying to solve, I think we can do this manually. In the reservation for the components in MD04, we can find the production/process orders where these reservations are pegged. During MRP run, PR will be created for these OrdRes. We can edit the PR and input production order number in field like "TRACKING NUMBER" in contact person tab of PR line item. During conversion of PR to PO, this field value is automatically copied to field "REQUIREMENT TRACKING NO." of purchase order line item. Hope this will help.

BR,
