• What is the cause and solution for SAP error message OM180 - No valuation classes were defined ?

  The SAP error message OM180 ("No valuation classes were defined") typically occurs in the context of materials management and inventory valuation. This error indicates that the system cannot find a valuation class for the material being processed, which is essential for determining how the material is valued in financial accounting.
  Cause:
  
  Missing Valuation Class: The most common cause of this error is that the material master record does not have a valuation class assigned. The valuation class is a key field that links the material to the appropriate general ledger accounts for inventory valuation.
  Incorrect Configuration: The configuration settings in the system may not be set up correctly, leading to the absence of valuation classes for certain material types or categories.
  Material Type Settings: The material type may not be configured to allow for valuation classes, or the valuation class may not be defined for the specific material type.
  Missing Account Determination: The account determination settings in the system may not be properly configured, leading to the inability to find the appropriate valuation class.
  
  Solution:
  
  
  Check Material Master Record:
  
  Go to the material master record (transaction code MM03).
  Check the Accounting view to see if a valuation class is assigned. If it is missing, you will need to update the material master with the correct valuation class.
  
  
  
  Define Valuation Classes:
  
  If the valuation class is missing, you may need to define it in the system. This can be done in the configuration settings:
  
  Navigate to SPRO ? Enterprise Structure ? Definition ? Logistics - General ? Define Valuation Classes.
  
  
  Ensure that the valuation classes are correctly linked to the appropriate general ledger accounts.
  
  
  
  Check Material Type Configuration:
  
  Ensure that the material type is configured to allow for valuation classes. This can be checked in the configuration settings under:
  
  SPRO ? Logistics - General ? Material Master ? Basic Settings ? Define Material Types.
  
  
  
  
  
  Account Determination:
  
  Verify the account determination settings to ensure that the valuation classes are correctly mapped to the appropriate accounts. This can be done in:
  
  SPRO ? Financial Accounting ? General Ledger ? Master Data ? G/L Accounts ? Define Account Determination.
  
  
  
  
  
  Consult Documentation: If you are unsure about the correct valuation class to use, consult your organization's documentation or reach out to your SAP support team for guidance.
