• What is the cause and solution for SAP error message /SCMTMS/FAG_MSG660 - Invalid unit of measure for item &1 ?

  The SAP error message /SCMTMS/FAG_MSG660 Invalid unit of measure for item &1 typically occurs in the context of SAP Transportation Management (TM) when there is an issue with the unit of measure (UoM) assigned to a specific item in a transportation document, such as a shipment or a freight order.
  Cause:
  
  Incorrect Unit of Measure: The unit of measure assigned to the item may not be valid or recognized in the system. This can happen if the UoM is not defined in the system or if it is not compatible with the product or material being used.
  Configuration Issues: There may be configuration issues in the material master or in the transportation management settings that lead to the invalid UoM.
  Data Inconsistencies: There could be inconsistencies in the data between the material master and the transportation document, such as changes made to the UoM after the document was created.
  Missing UoM Conversion: If the system requires a conversion between different units of measure and the conversion is not defined, this error can occur.
  
  Solution:
  
  Check the Unit of Measure: Verify that the unit of measure assigned to the item is valid. You can do this by checking the material master data (transaction code MM03) for the relevant material and ensuring that the UoM is correctly defined.
  Review Configuration: Ensure that the UoM settings in the configuration for both the material and the transportation management are correct. This may involve checking the settings in the customizing (transaction code SPRO).
  Update the Document: If the UoM has changed after the document was created, you may need to update the transportation document to reflect the correct UoM.
  Define UoM Conversions: If applicable, ensure that any necessary UoM conversions are defined in the system. This can be done in the material master or through the relevant configuration settings.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling UoM issues in SAP TM.
