• What is the cause and solution for SAP error message /SCMTMS/SCH549 - Deletion is not possible; departure ref. by departure &1 of schedule &2 ?

  The SAP error message /SCMTMS/SCH549 indicates that a deletion operation is not possible because the departure you are trying to delete is referenced by another departure in the schedule. This typically occurs in the context of SAP Transportation Management (TM) when you are trying to delete a transportation schedule or a related departure that is still linked to other objects.

  Solution:
  
  Check Dependencies: Investigate the schedule and the departures to identify which other departure is referencing the one you are trying to delete. You can do this by reviewing the transportation schedule in the SAP TM interface.
  Remove References: If possible, modify or delete the referencing departure or schedule first before attempting to delete the original departure.
  Use Transaction Codes: Utilize transaction codes like /SCMTMS/TS (Transportation Scheduling) to view and manage your transportation schedules and departures.
  Consult Documentation: Refer to SAP documentation or help files for more detailed information on managing transportation schedules and understanding the relationships between different objects.
