• What is the cause and solution for SAP error message LB091 - Units of measure transferred from the reference material ?

  The SAP error message LB091, which states "Units of measure transferred from the reference material," typically occurs in the context of inventory management or material management when there is a mismatch or inconsistency in the units of measure (UoM) between the reference material and the material being processed.
  Cause:
  
  Mismatch in Units of Measure: The error often arises when the units of measure defined for the reference material do not match those of the material being processed. This can happen during transactions like goods movements, stock transfers, or when creating purchase orders.
  Incorrect Configuration: The configuration settings for the material master data may not be set up correctly, leading to discrepancies in how units of measure are defined and used.
  Reference Material Issues: If the reference material has been changed or updated (e.g., UoM changed), it may lead to inconsistencies when trying to use it in transactions.
  
  Solution:
  
  
  Check Material Master Data: Review the material master data for both the reference material and the material being processed. Ensure that the units of measure are correctly defined and consistent.
  
  Go to transaction code MM03 to view the material master data.
  Check the "Units of Measure" tab to verify the UoM settings.
  
  
  
  Adjust UoM Settings: If there is a mismatch, you may need to adjust the units of measure for either the reference material or the material being processed. This can be done in the material master using transaction code MM02 (to change) or MM01 (to create).
  
  
  Review Configuration: If the issue persists, check the configuration settings in the SAP system related to units of measure. This can be done through the following:
  
  Transaction code SPRO to access the configuration settings.
  Navigate to the relevant sections under "Logistics" > "Material Management" > "Basic Settings" > "Units of Measure."
  
  
  
  Consult Documentation: If you are unsure about the correct UoM settings, refer to SAP documentation or consult with your SAP support team for guidance on how to properly configure units of measure.
  
  
  Testing: After making changes, perform a test transaction to ensure that the error does not occur again.
  
  
  Related Information:

  Material Master Views: The material master has various views (Basic Data, Purchasing, Sales, etc.) that may contain different UoM settings. Ensure that all relevant views are consistent.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP Notes can provide additional insights or solutions specific to your version of SAP.
