Use Customer Plan Schedule Maint (7.5.1) or Customer Ship Schedule Maint (7.5.2) to delete a customer trade sales schedule. When you delete the customer schedule, the system deletes the matching supplier schedule, as long as the system has not exported or printed the supplier schedule.

If the system exported or printed the supplier schedule, it does not delete it, and you cannot delete the customer schedule. The system displays an error message in Customer Plan Schedule Maint and Customer Ship Schedule Maint if you try.
