• What is the cause and solution for SAP error message WB2B519 - Sales Unit of Measure &1 was re-determined for material &2, Item &3 ?

  The SAP error message WB2B519 indicates that the sales unit of measure for a specific material has been re-determined during a sales order processing or related transaction. This typically occurs when there is a mismatch or inconsistency in the unit of measure settings for the material in question.
  Cause:
  
  
  Unit of Measure Configuration: The sales unit of measure for the material may not be correctly defined in the material master data. This can happen if the sales unit of measure is not maintained or if there are inconsistencies between the sales organization and the material master data.
  
  
  Material Master Data Changes: If there have been recent changes to the material master data, such as changes to the sales unit of measure or the base unit of measure, it can trigger this error.
  
  
  Sales Order Configuration: The sales order may be configured to use a different unit of measure than what is defined in the material master, leading to a re-determination.
  
  
  Custom Logic or User Exits: Custom logic or user exits in the sales order processing can also lead to this error if they manipulate the unit of measure in a way that conflicts with the standard SAP behavior.
  
  
  Solution:
  
  
  Check Material Master Data: 
  
  Go to the material master (transaction code MM03) and check the sales unit of measure for the material in question. Ensure that it is correctly defined and matches the expected sales unit for the sales organization.

  Check the sales order (transaction code VA03) to see if the unit of measure used in the order matches the unit of measure defined in the material master. If there is a discrepancy, correct it.
  
  
  
  Update Unit of Measure Settings: 
  
  If necessary, update the unit of measure settings in the material master to ensure consistency across all relevant views (Sales, Purchasing, etc.).
  
  
  
  Check for Custom Logic: 
  
  If there are any custom developments or user exits that might affect the unit of measure determination, review and adjust them as needed.
