• What is the cause and solution for SAP error message M3181 - Valuation class & not allowed for valuation type & ?

  The SAP error message M3181, which states "Valuation class & not allowed for valuation type &," typically occurs in the context of inventory management and material valuation in SAP. This error indicates that there is a mismatch between the valuation class assigned to a material and the valuation type that is being used in a transaction.
  Cause:
  
  
  Valuation Class Configuration: The valuation class assigned to the material does not match the allowed valuation types defined in the system. This can happen if the valuation class is not properly configured in the system or if the material is being used in a way that is not compatible with its valuation class.
  
  
  Material Master Data: The material master data may have incorrect or incomplete information regarding the valuation class or valuation type.
  
  
  Valuation Type Settings: The valuation type settings in the system may not include the valuation class that is being used for the material.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the valuation class assigned to the material.
  Ensure that the valuation class is correctly set up and corresponds to the intended valuation type.
  
  
  
  Review Valuation Class Configuration:
  
  Check the configuration of the valuation classes in the system (transaction code OMWB or SPRO path: Logistics > Materials Management > Valuation > Account Determination > Configure Automatic Postings).
  Ensure that the valuation class is allowed for the valuation type you are trying to use.
  
  
  
  Adjust Valuation Type Settings:
  
  If necessary, adjust the settings for the valuation type to include the valuation class in question. This may involve modifying the configuration in the system to allow the combination of valuation class and valuation type.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidance on how to resolve this error based on your system's configuration.
  
  
  
  Testing:
