Diagnosis
You would like to enter a new delivery schedule. The system, however,recognizes that you have already entered a new or already existingdelivery schedule in the current transaction.

System Response
The system does not let you enter a second new delivery schedule sothat there are no gaps in the delivery schedule history.

You can either change the current delivery schedule or save thescheduling agreement and then enter a new delivery schedule.
If this message appears in incoming processing for delivery scheduling,the IDoc finishes in status 51. You must then save the delivery planmanually in the change mode. After that you can process the IDoc again.
