Special stock indicator on the inbound delivery.
Wondering if someone can help me out. I am contacted by a client with the following challenge, all stock was previously held in consignment however for one finished material they have decided to purchase these as non-consignment. The PIR has been setup to reflect this and when the PO (ME21N) is created the K flag is not populated. Now when there 3PL (DC) creates an inbound delivery on the client's system the K flag is populated in the goods movement data thus indicating to store it physically as K in the warehouse but also receiving it in SAP as K.
My question: where is the K derived from when creating an inbound delivery.
Thank you in advance for your help.
