  The SAP error message "09242 Duplicate entries for add. unit of measure not allowed" typically occurs when there are duplicate entries for the additional unit of measure in the material master data. This can happen when you try to add or modify a material and the system detects that the additional unit of measure you are trying to enter already exists for that material.
  Cause:
  
  Duplicate Entries: The primary cause of this error is that the additional unit of measure you are trying to add already exists in the material master for the same material.
  Incorrect Data Entry: Sometimes, this can happen due to incorrect data entry or a misunderstanding of the required fields.
  Configuration Issues: There may be configuration settings in the system that enforce unique entries for additional units of measure.
  
  Solution:
  
  
  Check Existing Units of Measure:
  
  Go to the material master record (transaction code MM03) and check the existing additional units of measure for the material in question.

  Consult Documentation:
  
  Review SAP documentation or help files related to material master data management for further guidance on handling units of measure.
