• What is the cause and solution for SAP error message /SCMTMS/TRQ688 - &1: Volume is less than the summed-up volume of the subordinate items ?

  The SAP error message /SCMTMS/TRQ688 &1: Volume is less than the summed-up volume of the subordinate items typically occurs in the context of SAP Transportation Management (TM). This error indicates that the total volume of a transportation unit (like a shipment or a freight order) is less than the total volume of the items that are assigned to it. 
  Cause:
  
  Volume Mismatch: The primary cause of this error is that the total volume of the items (subordinate items) being assigned to a transportation unit exceeds the volume capacity of that transportation unit.
  Incorrect Data Entry: There may be incorrect data entries for the volume of the items or the transportation unit.
  Changes in Item Details: If the details of the items (like volume) were changed after the transportation unit was created, it could lead to this mismatch.
  Configuration Issues: There might be issues with the configuration of the transportation unit or the items in the system.
  
  Solution:
  
  Check Item Volumes: Review the volumes of the subordinate items assigned to the transportation unit. Ensure that the summed-up volume of these items is accurate.
  Adjust Transportation Unit Volume: If the transportation unit's volume is indeed less than the total volume of the items, you may need to increase the volume capacity of the transportation unit.
  Reassign Items: If the transportation unit cannot accommodate the items, consider reassigning the items to a different transportation unit that has sufficient capacity.
  Data Validation: Validate the data entries for both the items and the transportation unit to ensure there are no discrepancies.
  Review Changes: If there were recent changes to item details, review those changes to ensure they are reflected correctly in the transportation unit.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines related to transportation management and volume handling.
