Duplicate Purchase Requisition for same Sales Order Item with MRP run

[former_member621473]

Dear All,

We are using Make-to-order module in our company.

After we create 1 Sales Order with FERT material, system automatically generated 2 Raw material Purchase Requistions (with account assignment Category E) for the same Sales Order item.

My question is why duplicate PR in the system? Is it correct? How we can forbid duplicate PR?

Thank you very much!

For this Raw Material,

- MRP Type: PD;

- Lot Size: EX;

- Planned Delivery Time: 45 Days;

- Forcast Requirements Period Indicator: M;

- Availablity Check: Y2 Ind.Req.chng.CheckRs;

- BOM dependent requirement: 1 Individual requirements only;

------------------------------------------------------------------------------------------------------------------------------------------------------

When I checked MD04 and MD05,the earlier PR 10130574 is not shown in the list:

The PR 10130574 linked to Purchase Order and PR 10131395 has no PO linked.

Hello,

MRP exception message 20 Cancel process is there, sales order requirement date is 01/04/2019 and PO as supply available on 25/10/2019 which can not deliver the sales order on requested date. That's why MRP has created another purchase requisition as per the lead time against the sales order.

You can change the delivery date of purchase order close to the sale order and then rerun MRP with planing mode 3 delete and recreate and check the out come.

Or if you want system should consider the existing supply like PO for this sale requirement then maintain the rescheduling horizon in OMDW , fixed future receipts can be considered should to be selected here, make the new rescheduling horizon longer to cover the existing purchase order, and run MRP again.

Also read SAP note 205717 - MRP: 'redundant' procurement proposals and 25388 - MD01, MD02, MD03: Rescheduling proposals: Documentation.

Dear Brahmankar,

Thank you fro your kindly reply.

If we keep using the PO 4500006768 which marked as 20 - cancel processing and complete the MIGO according to this PO, what will happen?

If we convert the PR 10131395 to one new PO, and MIGO again, what will happen?

Does system assign 2 times cost or 2 items in stock?

Best regards.

Hello,

Why don't you test this in your quality system?

Yes you will have double the inventory as two PO for same sales order. That's why you have exception message 20 cancel process.

Best Regards,
