• What is the cause and solution for SAP error message WZRE_QUAR023 - Classical FI Interface call is not longer supportet, see long text ?

  The SAP error message:
  WZRE_QUAR023: Classical FI Interface call is not longer supportet, see long text
  
  Cause:
  This error occurs because the classical FI (Financial Accounting) interface, which was used in older SAP systems for posting financial documents, has been deprecated and is no longer supported in the current SAP system or component you are using. SAP has moved to newer interfaces and technologies (such as the BAPI-based or API-based interfaces) for financial postings.
  The message indicates that your system or a custom program is still trying to use the old classical FI interface calls, which have been disabled or removed in the current SAP release or patch level.
  
  Solution:
  
  
  Check the Long Text of the Message:
  The long text usually provides more detailed information and possibly points to the new interface or method to be used.
  
  
  Update the Interface Calls:
  
  Identify the program, user-exit, BAdI, or custom code that is calling the classical FI interface.
  Replace the classical FI interface calls with the new supported interface. This typically means:
  
  Using BAPIs such as BAPI_ACC_DOCUMENT_POST for posting FI documents.
  Using the new API or function modules recommended by SAP for financial postings.
  
  
  
  
  
  Consult SAP Notes and Documentation:
  
  Search for SAP Notes related to message WZRE_QUAR023 or the classical FI interface deprecation.
  SAP Notes often provide detailed instructions on migration paths from classical interfaces to new ones.
  
  
  
  Testing:
  
  After updating the interface calls, thoroughly test the financial postings to ensure correctness and completeness.
  
  
  
  
  Related Information:
  
  The classical FI interface was commonly used in older SAP releases (e.g., R/3 systems).
  SAP has been encouraging customers to move to BAPI-based or API-based interfaces for better integration, error handling, and support.
  The error message is a safeguard to prevent usage of obsolete interfaces that may cause data inconsistencies or are not supported in newer SAP versions.
  If you are using third-party add-ons or legacy custom code, coordinate with the vendor or development team to update the interface usage.
  
  
  Summary:
  
  Cause: Use of deprecated classical FI interface calls.
  Solution: Replace classical FI interface calls with supported BAPI or API calls (e.g., BAPI_ACC_DOCUMENT_POST).
  Check: Long text of the message and SAP Notes for detailed guidance.
