This error indicates that a specific unit of measure is not assigned to a material or a relevant object, which is necessary for processing transactions involving that material.
  Cause:
  
  Missing UoM Assignment: The primary cause of this error is that the unit of measure (UoM) you are trying to use is not assigned to the material or object in question.
  Incorrect Configuration: There may be a configuration issue in the UoM settings or the material master data.

  Solution:
  
  
  Check Material Master Data:

  Review UoM Configuration:
  
  Check the configuration settings for UoM in the SAP system (transaction code OMN1 for defining UoM).

  Check for Data Consistency:
