Smart SAP Assistant

• What is the cause and solution for SAP error message /SCTM/TMMD_UI143 - You cannot change the zone type for a leg zone ?

  The SAP error message /SCTM/TMMD_UI143 indicates that you are trying to change the zone type for a leg zone in the Transportation Management (TM) module, but the system does not allow this action. This restriction is typically in place because certain configurations or data integrity rules prevent modifications to specific attributes of leg zones once they have been defined.
  Cause:
  
  Data Integrity Rules: The system enforces rules to maintain data integrity. Once a leg zone is created and used in transportation planning, changing its type could lead to inconsistencies in the planning and execution processes.
  Dependencies: The leg zone may have dependencies or relationships with other objects (like routes, shipments, etc.) that prevent changes to its type.
  Configuration Settings: The system may be configured in a way that restricts changes to certain attributes of leg zones after they have been established.
  
  Solution:
  
  Review the Leg Zone: Check the current configuration of the leg zone to understand its dependencies and usage. If it is actively used in planning or execution, consider creating a new leg zone with the desired type instead of modifying the existing one.
  Create a New Leg Zone: If you need a different zone type, create a new leg zone with the correct type and use it in your planning processes.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing leg zones and their attributes.
  Contact SAP Support: If you believe that the change should be allowed based on your business process, consider reaching out to SAP support for further assistance or to understand if there are any configuration settings that can be adjusted.
