• What is the cause and solution for SAP error message VT820 - Calculation type reference cond. type not equal to calc. type cond. type ?

  The SAP error message VT820, which states "Calculation type reference cond. type not equal to calc. type cond. type," typically occurs in the context of pricing conditions in SAP, particularly when dealing with condition types in pricing procedures.
  Cause:
  This error usually arises when there is a mismatch between the calculation types of the reference condition type and the condition type being used in the pricing procedure. Each condition type in SAP has a specific calculation type that determines how the condition is processed (e.g., whether it is a discount, surcharge, or fixed amount). If the condition types are not compatible or if there is an inconsistency in the configuration, this error will be triggered.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Condition Types: 
  
  Go to the transaction code V/06 (for condition types) and review the configuration of the condition types involved. Ensure that the calculation types are compatible.
  Verify that the reference condition type and the condition type being used have the same calculation type.
  
  
  
  Review Pricing Procedure:
  
  Use transaction code V/08 to check the pricing procedure where the error occurred. Ensure that the condition types are correctly assigned and that their calculation types are compatible.
  
  
  
  Adjust Configuration:
  
  If you find that the calculation types are indeed different, you may need to adjust the configuration of either the reference condition type or the condition type in question to ensure they match.
  
  
  
  Test Changes:
  
  After making any changes, perform a test transaction to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of changing condition types or pricing procedures, consult SAP documentation or seek assistance from a functional consultant with expertise in pricing.
