Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Unit of Measure: The specified unit of measure (UoM) does not exist in the system. This can happen if the UoM has not been defined in the system or if it has been deleted.
  Incorrect Configuration: The material may be configured to use a UoM that is not recognized or is not set up correctly in the system.
  Master Data Issues: There may be inconsistencies or errors in the material master data, particularly in the UoM settings.
  
  Solution:
  
  
  Check UoM Configuration:
  
  Go to transaction code CUNI (Unit of Measure Conversion) in SAP.
  Verify if the unit of measure &1 (replace &1 with the actual UoM mentioned in the error) exists in the system.
  If it does not exist, you will need to create it.

  Transport Requests:
  
  If the UoM was recently created or modified in a development environment, ensure that the changes have been transported to the production environment.
