• What is the cause and solution for SAP error message CMM_TIER_PRC025 - Change of item quantity not possible since UoMs are not consistent ?

  The SAP error message CMM_TIER_PRC025 indicates that there is an inconsistency in the Units of Measure (UoMs) when trying to change the quantity of an item in a document, such as a purchase order or sales order. This error typically arises when the system detects that the UoMs for the item being modified do not match the expected UoMs defined in the system.
  Cause:
  
  Inconsistent UoMs: The item may have different UoMs defined in various places (e.g., in the material master, purchase order, or sales order).
  Conversion Issues: There may be issues with the conversion factors between the base UoM and the UoM being used in the document.
  Incorrect Settings: The settings in the material master or the document may not align, leading to discrepancies.
  Multiple UoMs: If the item is set up with multiple UoMs (e.g., base UoM, sales UoM, purchase UoM), and the system cannot reconcile them during the quantity change.
  
  Solution:
  
  
  Check Material Master: Verify the UoM settings in the material master record. Ensure that the base UoM, sales UoM, and purchase UoM are correctly defined and consistent.
  
  Transaction Code: MM03 (Display Material)
  
  
  
  Review Document UoMs: Check the UoMs used in the document (e.g., purchase order or sales order) and ensure they match the UoMs defined in the material master.
  
  Transaction Code: ME23N (Display Purchase Order) or VA03 (Display Sales Order)
  
  
  
  Adjust Quantities: If you need to change the quantity, ensure that you are using the correct UoM that is consistent with the material master. If necessary, convert the quantity to the appropriate UoM before making the change.
  
  
  Check UoM Conversion: If there are conversion factors defined, ensure they are correct and that the system can convert between the UoMs without issues.
  
  
  Consult Documentation: Review SAP documentation or help resources for specific guidance on handling UoM issues in your version of SAP.
  
  
  Contact Support: If the issue persists after checking the above, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on handling UoM inconsistencies.
  Training: Consider training sessions or resources on SAP material management and UoM handling to better understand the implications of UoM settings in your processes.
