• What is the cause and solution for SAP error message /SCMTMS/VSS_ENGINE055 - Un-/coupling of TU &2 can't be sched. between latest start and end date ?

  The SAP error message /SCMTMS/VSS_ENGINE055 indicates that there is an issue with scheduling the un-coupling or coupling of a Transportation Unit (TU) within the specified time constraints. Specifically, it means that the operation cannot be scheduled between the latest start and end dates defined for the Transportation Unit.
  Cause:
  
  
  Time Constraints: The latest start and end dates for the Transportation Unit do not allow for the requested un-coupling or coupling operation to be scheduled. This could be due to:
  
  The operation being requested is outside the defined time window.
  The Transportation Unit is already scheduled for another operation during that time.
  
  
  
  Planning Parameters: The planning parameters or settings in the system may not allow for the requested operation to occur within the specified time frame.
  
  
  Resource Availability: There may be a lack of available resources (e.g., vehicles, drivers) to perform the operation within the required time.
  
  
  Solution:
  
  
  Check Time Constraints: Review the latest start and end dates for the Transportation Unit. Ensure that the requested un-coupling or coupling operation falls within these dates. If necessary, adjust the time constraints to allow for the operation.
  
  
  Adjust Scheduling: If the operation is indeed outside the allowed time frame, consider rescheduling the operation to a time that fits within the defined constraints.
  
  
  Review Planning Parameters: Check the planning parameters in the SAP system to ensure they are set correctly. This may involve reviewing the configuration settings for transportation planning.
  
  
  Resource Management: Ensure that the necessary resources are available for the operation. If resources are not available, consider adjusting the schedule or reallocating resources.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for additional guidance on managing Transportation Units and scheduling operations.
