• What is the cause and solution for SAP error message FRE128 - Contract &1 Item &2 not used - Different Unit of Measure ?

  The SAP error message FRE128 indicates that there is a discrepancy in the unit of measure (UoM) between the contract item and the item being processed. This typically occurs in the context of contract management, where the system expects the unit of measure for a specific contract item to match the unit of measure of the item being referenced in a transaction (such as a purchase order or delivery).
  Cause:
  
  Unit of Measure Mismatch: The most common cause of this error is that the unit of measure defined in the contract item does not match the unit of measure of the item being processed. For example, if the contract specifies that the item is to be measured in "pieces" but the transaction is trying to use "boxes," this error will occur.
  Incorrect Configuration: There may be issues with how the units of measure are configured in the system, leading to inconsistencies.
  Data Entry Errors: Manual entry errors when creating contracts or processing transactions can lead to mismatched units of measure.
  
  Solution:
  
  Check Contract Details: Review the contract and the specific item to ensure that the unit of measure is correctly defined. You can do this by navigating to the contract in the SAP system and checking the item details.
  Adjust Transaction UoM: If the contract is correct, ensure that the transaction you are trying to process uses the same unit of measure as defined in the contract. You may need to change the UoM in the transaction to match the contract.
  Update Contract: If the transaction needs to use a different unit of measure, consider updating the contract to reflect this change, if appropriate.
  Consult Configuration: If the issue persists, consult with your SAP configuration team to ensure that the units of measure are set up correctly in the system. This may involve checking the configuration settings for material master data and contract management.
  Training and Documentation: Ensure that users are trained on the importance of matching units of measure and that there is documentation available to guide them in the process.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like ME33K (Display Contract) to view contract details and ME21N (Create Purchase Order) to create or modify purchase orders.
  Unit of Measure Configuration: The configuration of units of measure can be found in the material master (transaction MM02) and may involve settings in the customizing (SPRO) area.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues or bugs related to this error message.
  
  By following these steps, you should be able to resolve the FRE128 error and ensure that your contract and transaction units of measure are aligned.
