• What is the cause and solution for SAP error message 881123 - UM &1 is already reference UM for all sales units not defined in REA ?

  The SAP error message 881123 indicates that there is an issue with the configuration of sales units in the system. Specifically, the message states that a certain unit of measure (UM) is already referenced for all sales units that are not defined in the REA (Revenue Accounting and Reporting) configuration.
  Cause:
  
  Duplicate Unit of Measure: The error typically arises when there is an attempt to assign a unit of measure that is already in use for other sales units, but those sales units are not properly defined in the REA settings.
  Configuration Issues: There may be a misconfiguration in the REA settings or in the unit of measure settings within the sales document or material master.

  Go to the transaction code CUNI (Unit of Measure Conversion) and verify the configuration of the units of measure. Ensure that the units are not duplicated and are correctly defined.
  
  
  
  Review REA Configuration:

  Make sure that the sales units you are trying to use are included in the REA settings.
  
  
  
  Adjust Sales Document Settings:
  
  If the error occurs during sales order creation or processing, check the sales document type and item category settings to ensure they are correctly configured to use the appropriate units of measure.
