• What is the cause and solution for SAP error message WZRE_PRX_MAPPING057 - ActionCode '02' (Change): Neither InvoiceID nor BillFromID are maintained ?

  The SAP error message:
  WZRE_PRX_MAPPING057 ActionCode '02' (Change): Neither InvoiceID nor BillFromID are maintained
  
  Cause:
  This error occurs during the processing of a proxy message (often related to invoice or billing document processing) when the system expects either an InvoiceID or a BillFromID to be provided for an action code '02' (which typically means "Change" or "Modify"). 
  
  The message indicates that neither the InvoiceID nor the BillFromID fields are filled in the incoming data.
  These fields are mandatory identifiers for the system to locate the existing invoice or billing document to be changed.
  Without these IDs, the system cannot determine which document to update, hence the error.
  
  
  Explanation of Terms:
  
  ActionCode '02' (Change): This action code signals that the incoming message intends to modify an existing document.
  InvoiceID: Unique identifier of the invoice document.
  BillFromID: Identifier of the billing party or the source of the invoice.
  
  
  Solution:
  
  
  Check the Incoming Data:
  
  Verify the proxy or IDoc data that triggers this error.
  Ensure that either InvoiceID or BillFromID is correctly populated in the message payload.
  If you are using a middleware or external system to send data to SAP, check the mapping and data extraction logic.
  
  
  
  Correct the Data Source:
  
  If the data is coming from an external system, fix the interface to send the required identifiers.
  If the data is manually entered or uploaded, ensure the fields are not left blank.
  
  
  
  Review the Proxy or IDoc Mapping:
  
  Check the proxy or IDoc structure for the message type involved.
  Confirm that the fields for InvoiceID or BillFromID are mapped correctly and mandatory fields are enforced.
  
  
  
  SAP Configuration:
  
  In some cases, the error might be due to missing configuration in the billing or invoicing process.
  Verify the configuration of the billing document types and related partner functions.
  
  
  
  Debugging:
  
  If the issue persists, debug the proxy or IDoc processing function module to see why these fields are not populated.
  Check the enhancement or user-exit implementations that might affect these fields.
  
  
  
  
  Related Information:
  
  This error is common in scenarios involving billing document changes via proxy or IDoc interfaces.
  The message is part of SAP's error handling in the Invoice Verification or Billing modules.
  Action codes typically follow the standard:
  
  '01' = Create
  '02' = Change
  '03' = Delete
  
  
  Always ensure that for 'Change' or 'Delete' actions, the system can uniquely identify the document to be processed.
