• What is the cause and solution for SAP error message KK555 - Unit of measure was changed ?

  The SAP error message KK555 ("Unit of measure was changed") typically occurs in the context of controlling (CO) when there is a discrepancy between the unit of measure (UoM) used in a cost object (like a cost center or internal order) and the unit of measure expected by the system for a particular transaction or posting.
  Cause:
  
  Unit of Measure Change: The error usually arises when the unit of measure for a material or cost object has been changed after it was initially set up. This can happen due to changes in the material master data or configuration settings.
  Inconsistent Data: If the unit of measure in the transaction does not match the unit of measure defined in the master data, the system will throw this error.
  Transaction Type: Certain transactions may require specific units of measure, and if the transaction is trying to use a different unit, it will lead to this error.
  
  Solution:
  
  Check Material Master Data: Verify the unit of measure settings in the material master (transaction code MM03). Ensure that the unit of measure used in the transaction matches the one defined in the material master.
  Review Cost Object Settings: Check the settings for the cost object (like internal orders or cost centers) to ensure that the unit of measure is consistent with what is expected for the transactions being processed.
  Adjust Transaction Data: If the unit of measure in the transaction is incorrect, adjust it to match the expected unit of measure.
  Consult Configuration: If the issue persists, consult with your SAP configuration team to review the settings related to units of measure in the controlling module.
  Recreate the Transaction: In some cases, it may be necessary to delete and recreate the transaction with the correct unit of measure.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), KK01 (Create Internal Order), and KK02 (Change Internal Order) to check and modify the necessary data.
