3614454 - Message: "You cannot change certain field values; PMR exists for component XXX" - Message No. /SPE/MAN025

When attempting to modify a component in a production order that is already distributed to EWM and linked to a PMR (Production Material Request), the following error is displayed upon saving:

• "You cannot change certain field values; PMR exists for component XXX"
  Message no. /SPE/MAN025

SAP S/4HANA Cloud Public Edition.

1. Open the Change Production/Process Order app.
2. Enter the production order number.
3. Modify an attribute of one of the assigned components (e.g., material number or batch).
4. Attempt to save the order.
5. Observe the error message.

The production order is already distributed to EWM, and a PMR document exists for the component. In such cases, certain changes to component attributes (such as changing the material number) are restricted, as they impact the synchronization between the ERP system and EWM.

To adjust component data in this scenario, follow the correct process:

1. Do not directly change the material number or batch on the existing component line.
2. Instead, delete the component that requires modification.
3. Re-add the component with the updated values (e.g., new material or batch).
4. Saving the order will trigger the necessary update to the PMR in EWM.

This approach ensures proper synchronization between the ERP production order and the associated PMR in EWM.
