I have a problem related to CO06, error message AG755: "Please select a line that can be changed".
When I enter to a specific material/plant in CO06, I can see that all the lines are confirmed and black. Any of the sales orders confirmed appear in blue, meaning able to change the confirmation.
I have been reading all similar issues and I can say that the problem is NOT coming from:
- Confirmation at storage location level (1773701 Note)
- Product Selection Item (1773701 Note)
- Running ATP_VBBE_CONSISTENCY. Programchecks and everything OK, no differences.
Am I missing something else?
What could be the cause of this error?
