Diagnosis
A schedule line for material &V1& in plant &V2& is not confirmed. Thiscan be due to one of the following causes:

• There was a date shift because of the delivery scheduling.

During the update of a confirmation for a sales scheduling agreementitem, a delivery was scheduled for the schedule lines to be updated.Here the material availability date is determined from the requesteddelivery date in backward scheduling. If, as a result of scheduling, thesystem finds a date that is in the past, the system switches to forwardscheduling, possibly from the current date. Schedule lines are createdin the results. The schedule lines are different from those thatoriginate from the APO system.

• The assignment of schedule line categories to the sales document item
type is incorrect.
To confirm all schedule lines when updating the sales documents, it isnecessary that the schedule lines that are relevant for delivery or MRPare assigned to the item category of the sales document.

System Response
The system terminates the processing, because a delivery schedule for ascheduling agreement can only be created if the schedule lines areconfirmed according to the appointments and quantities transferred.

Procedure
Check the following system settings:


• In transaction OVLY (Sales Documents: Types -
Scheduling) check whether the "Backward Scheduling Only" indicator isset for the type of sales document to be updated. If not, set theindicator, and start the transfer from the APO system again.

• In transaction VOV5

(Assign Schedule Line Categories), check whether the correct scheduleline categories are assigned to the type of sales document items to betransferred. If not, assign the correct schedudule line categories, andstart the transfer from the APO system again.
