• What is the cause and solution for SAP error message VF_PRC_CPF003 - Data Source Routine &1: parameter &2 must be of type &3 ?

  The SAP error message:
  VF_PRC_CPF003 Data Source Routine &1: parameter &2 must be of type &3
  
  Meaning / Cause
  This error occurs during the billing document pricing procedure when a user-defined or standard Data Source Routine (a user-exit or enhancement routine used in pricing) is called with parameters that do not match the expected data types.
  
  &1 = Name of the Data Source Routine (e.g., a function module or form routine)
  &2 = Name of the parameter passed to the routine
  &3 = Expected data type of the parameter
  
  The message indicates that the parameter &2 passed to the routine &1 is not of the expected data type &3. This mismatch can happen if the routine is called incorrectly, or if the routine's interface has been changed but the calling program was not updated accordingly.
  
  Common Causes
  
  Custom coding in pricing user-exits (e.g., in routines like RV61AFZZ, RV61AFZ1, or other user-defined routines) where parameters are incorrectly declared or passed.
  Changes in SAP standard or custom routines without adjusting the calling parameters.
  Incorrect implementation of pricing routines or data source routines in the pricing procedure.
  Transport or system copy issues where routine definitions or interfaces are inconsistent.
  
  
  Solution / How to Fix
  
  
  Check the Routine Definition:
  
  Identify the routine &1 mentioned in the error.
  Review the interface of this routine (parameters and their data types).
  Compare the expected parameter types with what is actually passed.
  
  
  
  Correct the Parameter Types:
  
  Adjust the calling program or the routine itself so that the parameter &2 matches the expected data type &3.
  This may involve changing variable declarations, casting, or modifying the routine interface.
  
  
  
  Review Custom Enhancements:
  
  If the routine is a custom enhancement or user-exit, check the implementation in transaction SMOD/CMOD or the relevant enhancement framework.
  Ensure that the parameters passed to the routine conform to the expected types.
  
  
  
  Check SAP Notes:
  
  Search for SAP Notes related to the specific routine or error message.
  Sometimes SAP provides corrections or guidance for known issues.
  
  
  
  Debugging:
  
  Use the debugger to trace the call to the routine and inspect the parameters.
  Verify the data types at runtime.
  
  
  
  Consult Documentation:
  
  Review SAP documentation for the pricing procedure and data source routines.
  Check the standard interface definitions in the SAP pricing routines.
  
  
  
  
  Related Information
  
  Pricing routines and user-exits: SAP pricing allows custom routines to be called during pricing to influence price calculation. These routines have strict interface definitions.
  Transaction codes:
