Error MM326 when trying to change profit center for Material

Hi,

The scenario is as below:

• Our users want to change the profit reporting for certain materials
• They want to change the profit center
• Before trying to do this they have done the following:
  • Removed all stock for these materials
  • Either deleted POs or created invoices for remaining POs(no pending qty.)

Despite trying this , we are facing same issue.

Now I know that i can resolve this issue by changing the message for MM326 from "Error" to "Warning" in OMT4.

However, is there any note or document from SAP that endorses this approach ?

Is there any other alternative to change material profit center under this situation?

Thanks

Akash
