Old Material Numbers will be maintained in&nbsp;MARA-BISMT. Stock will be moved to new material code. I have a few questions regarding this.</P><P>1. Should existing Purchase Orders and Sales Orders be closed before I do this activity? Or is there a way to use the new material codes to do goods receipt for existing POs and deliveries for existing SOs?</P><P>2. How do I handle sales return of older sales orders?</P> Wed, 05 Jun 2024 06:12:35 GMT https://community.sap.com/t5/enterprise-resource-planning-q-a/how-to-handle-purchase-orders-and-sales-orders-with-old-material-numbers/qaq-p/13721521 ranjithjoy 2024-06-05T06:12:35Z Re: How to handle Purchase Orders and Sales Orders with Old Material Numbers? https://community.sap.com/t5/enterprise-resource-planning-q-a/how-to-handle-purchase-orders-and-sales-orders-with-old-material-numbers/qaa-p/13726678#M4188404 Hope you tried the option of Material substitution(VB11/12/13) for such scenarios?
