MB22 - Profit center not updated
I got a situation that an internal order tagged with a profit center A. Later when I create a reservation with reference to order (MB21/22/23), this profit center will carry to the reservation document. When I decided to use another profit center "B" in the internal order, I went back to change in the internal order. Subsequently, I went back to the reservation document posted earlier with change mode, when I double click on the item and click on the "back" button, the system will prompt me with the "Profit center was reset to profit center B" and meantime, I can see the value has been changed in the document, and therefore I save the reservation document. But, weird things coming in, when I opened up the reservation document again, the profit center was still showing the old profit center code. Any idea why and how to workaround it?
Thanks for your helpful guidelines.
