This error typically occurs in scenarios such as inventory management, sales order processing, or production planning when the system checks the UoM against the allowed units defined in the material master.
  Cause:
  
  Incorrect UoM: The UoM entered in the transaction does not match any of the allowed UoMs defined in the material master for that specific material.
  Material Master Configuration: The material master may not have the required UoM set up correctly. This could be due to missing entries in the UoM fields or incorrect settings.

  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Sales Org. Data" views to see the allowed UoMs.
  Ensure that the UoM you are trying to use is listed in the allowed UoMs for the material.
  
  
  
  Change UoM in Transaction:
  
  If the UoM is incorrect, change it to one of the allowed UoMs as per the material master.
  
  
  
  Update Material Master:
  
  If you need to use a different UoM that is not currently allowed, you may need to update the material master to include this UoM.

  Consult with Configuration Team:
