• What is the cause and solution for SAP error message WZRE_PRX_MAPPING028 - Item &1: BTDTypeCode &2 of referenced document &3 is not supported ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_PRX_MAPPING028 Item &1: BTDTypeCode &2 of referenced document &3 is not supported
  
  Meaning / Cause:
  This error occurs during the processing of electronic documents (e.g., e-invoices, e-orders) in SAP, particularly in scenarios involving Business Transaction Document (BTD) Type Codes. The message indicates that the system encountered a referenced document with a BTDTypeCode that is not supported or recognized by the current configuration or mapping in the SAP system.
  
  Item &1: The item number or line in the document where the error occurred.
  BTDTypeCode &2: The Business Transaction Document Type Code that is not supported.
  Referenced document &3: The document number or identifier that contains the unsupported BTDTypeCode.
  
  The BTDTypeCode is a key identifier used in electronic document exchange to specify the type of business transaction (e.g., invoice, credit memo, order confirmation). If the code is not mapped or recognized, the system cannot process the document correctly.
  
  Common Causes:
  
  The BTDTypeCode in the referenced document is new or custom and has not been maintained in the SAP system.
  Missing or incomplete configuration in the Electronic Document Processing or IDoc / XML mapping settings.
  The document type is not supported by the current version of the electronic document interface or middleware.
  Incorrect or inconsistent data in the referenced document.
  
  
  Solution / How to Fix:
  
  
  Check the BTDTypeCode:
  
  Identify the exact BTDTypeCode (&2) causing the issue.
  Verify if this code is valid and expected for your business process.
  
  
  
  Maintain BTDTypeCode Mapping:
  
  Go to the relevant customizing transaction or IMG path for electronic document processing.
  For example, in SAP S/4HANA or ECC, check the configuration under:
  
  SPRO ? Logistics Invoice Verification ? Electronic Invoice Processing ? Maintain BTD Type Codes
  Or the equivalent path for your module (SD, MM, FI).
  
  
  Add or update the mapping for the missing BTDTypeCode so that the system recognizes it.
  
  
  
  Update or Enhance the Mapping Program:
  
  If you are using middleware or custom mapping programs (e.g., in SAP PI/PO or SAP Cloud Integration), ensure that the BTDTypeCode is handled correctly.
  Update the mapping logic to support the new or custom BTDTypeCode.
  
  
  
  Check the Referenced Document:
  
  Verify the referenced document (&3) for correctness.
  Ensure that the document type and BTDTypeCode are consistent and valid.
  
  
  
  Apply SAP Notes / Patches:
  
  Check SAP Support Portal for any relevant SAP Notes that address this error or add support for new BTDTypeCodes.
  Apply corrections or patches if available.
  
  
  
  Testing:
  
  After configuration changes, test the document processing again to confirm the error is resolved.
  
  
  
  
  Related Information:
  
  BTDTypeCode: Business Transaction Document Type Code is a standard code used in electronic document exchange to identify the type of business document.
  This error is common in e-invoicing, e-ordering, or electronic document interchange (EDI) scenarios.
  The error message is part of the WZRE_PRX_MAPPING message class, which relates to proxy or mapping errors in electronic document processing.
  Consult SAP documentation on Electronic Document Processing and BTD Type Codes for your specific SAP release.
  If using SAP middleware (PI/PO, CPI), check the integration flow and mapping steps for handling BTDTypeCode.
  
  
  If you provide the exact SAP module or scenario (e.g., FI-CA, MM-IV, SD billing), I can give more tailored instructions.
  
  Summary:
  
  The error means the system encountered an unsupported BTDTypeCode in a referenced document. To fix it, maintain or extend the BTDTypeCode mapping in your SAP configuration or middleware so that the system recognizes and processes the document correctly.
