• What is the cause and solution for SAP error message FKKBIX2451 - Exception reason &1 does not match processing rule 3 for schema &2 ?

  The SAP error message FKKBIX2451 indicates that there is a mismatch between the exception reason specified in the processing of a financial document and the processing rules defined in the schema for that document. This typically occurs in the context of financial accounting, particularly when dealing with payment processing or invoice verification.
  Cause:
  The error arises when:
  
  An exception reason (like a specific code or identifier that indicates why a document is being processed differently) is not aligned with the rules defined in the schema for processing that type of document.
  The schema (which defines how different types of documents should be processed) does not recognize the exception reason being used, leading to a conflict.

  Check Exception Reason: Verify the exception reason being used in the transaction. Ensure that it is valid and correctly entered.
  
  
  Review Processing Rules: Examine the processing rules defined in the schema (transaction code: OBPM1 for payment processing rules). Ensure that the exception reason is included in the rules for the schema you are using.
  
  
  Adjust Schema Configuration: If the exception reason is valid but not included in the schema, you may need to modify the schema configuration to accommodate this exception reason. This may involve:
  
  Adding the exception reason to the relevant processing rules.
  Ensuring that the schema is correctly assigned to the relevant document types.
  
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on how to configure processing rules and exception reasons.
