  Cause:
  
  Invalid Unit of Measure: The unit of measure being used (represented by &1 in the error message) is not recognized or is not set up in the system for the specific material or transaction type.

  Solution:
  
  Check Unit of Measure: Verify that the unit of measure you are trying to use is valid and correctly spelled. Ensure that it is the appropriate UoM for the transaction you are performing.
  Review Material Master: Go to the material master record (transaction code MM03) and check the "Units of Measure" tab to see if the UoM is defined for the material in question.
  Configuration Settings: If you have the necessary authorizations, check the configuration settings in the SAP system (transaction code SPRO) to ensure that the unit of measure is allowed for the relevant transaction type or material.
