WIP Batches and Subcontracting

Happy New Year All,

I'm trying to get WIP batches working so that a partially finished material for a production order can be sent to a supplier as we need to show that the WIP is with the vendor (full traceability). There are several subcontracting operations in sequence and I come to learn that before Ehp 4 it wasn't possible to achieve this and why WIP batches was introduced.

I've made, I think all of the necessary system settings (activated the business extension, switched on WIP batches, changed the confirmation screen to show the WIP batch entry sections, applied OSS note 1251288 and created a non-valuated reference material which is assigned to the header material of the BOM in the Work Scheduling tab of the material master) which from what I can see is everything that I need to do.

I've then created a production order with let's say internal operation 0010 with components A & B assigned, external operation 0020 for the painting of the WIP component from op 0010 and another external operation for the testing of 0010 of the WIP component from op 0010 after it has been painted and delivered back to our factory.

I then release and confirm operation 0010 and at the same time create a WIP batch for the reference material which I can see is being posted into blocked stock. The next step is to convert the purchase requisition which was created when the production order was released to a purchase order (2 PR line items covering ops 0020 and 0030) however, when I do this the system returns an error message stating "not possible to determine any components". I also see that the reference material isn't being populated on the PO line item (no material number and text of op 0020) as I'm lead to believe it should do. I was therefore wondering if anyone had experienced this and knew possibly what I was doing wrong or make any suggestion? Thanks in advance for any help offered.

    I am not sure on reference material population in subcontracting PR created by production order release. Can you assign the reference material to the subcontracting PR manually?

    In standard, the subcontracting PO should have components assigned to it. So you assign the WIP reference material with the WIP batch created to the subcontracting PO and process the PO.

      Hi Ravi,

      Thanks for responding. Do you know if the materials which are being issued to the production order need to be batch managed? Currently they aren't so I'm going to try and set them as batch managed to see if it changes anything.
