3688545 - "Purchase requisition item has a different material number", warning shown instead of error while converting PR to PO

• Purchase requisition item material number differs from the material number in the Purchase Order, leading to a mismatch.
• Error message displayed: "Message no. 06056 – Purchase requisition … item … has a different material number".
• Warning message shown instead of an error when attempting to create a Purchase Order with a different material number.

SAP S/4HANA Cloud Public Edition

1. Create a purchase requisition for a specific material number.
2. Use the purchase requisition to create a purchase order.
3. Change the material number in the purchase order screen.
4. Observe that the system allows the creation of the purchase order with only a warning message, instead of an error message.

This is standard system design in SAP S/4HANA Cloud Public Edition. By default:

• When adopting PR items into PO, SAP checks if the material is changed.

• SAP issues a warning message only (Message No. 06056).

• The system does not prevent the PO from being created.

SAP allows buyers to intentionally replace material codes for business scenarios such as substitute materials, procurement of alternative items, or free-text PR conversion. If the user wants the system to block PO creation when the PR material and PO material differ, this must be implemented via custom logic in SAP S/4HANA Cloud. 

Create an implementation for BAdI BD_MMPUR_FINAL_CHECK_PO. With this BAdI, it is possible to implement own checks before a purchase order is saved.
