Smart SAP Assistant

• What is the cause and solution for SAP error message WRPC_XI_PROXY002 - Fill mandatory section &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRPC_XI_PROXY002: Fill mandatory section &1
  
  Cause:
  This error occurs when a mandatory section or field in the XI (Exchange Infrastructure) proxy message is not filled or is missing during the processing of a proxy message. The placeholder &1 typically indicates the name of the mandatory section or field that is missing.
  In SAP PI/PO or SAP XI scenarios, proxy messages have certain mandatory segments or fields defined in the message structure (based on the underlying XML schema). If these mandatory parts are not populated, the runtime raises this error to indicate incomplete or invalid message content.
  
  Common Scenarios Leading to This Error:
  
  The inbound or outbound proxy message is missing required data.
  The mapping or data transformation did not populate mandatory fields.
  The sender system did not send all required data.
  Manual testing or message simulation missed mandatory fields.
  Incorrect or incomplete message structure in the proxy interface.
  
  
  Solution:
  
  
  Identify the Missing Section:
  
  Check the error message text or logs to find the exact mandatory section or field name indicated by &1.
  Review the proxy interface definition (in the Enterprise Services Repository or Integration Directory) to understand which fields are mandatory.
  
  
  
  Check the Message Payload:
  
  Analyze the XML payload of the proxy message.
  Verify that all mandatory fields/sections are present and correctly filled.
  
  
  
  Review Mapping and Data Sources:
  
  If a mapping is involved, ensure that the mapping logic populates all mandatory fields.
  Check the source system or sender application to confirm it sends all required data.
  
  
  
  Test with Complete Data:
  
  Use test data that includes all mandatory fields.
  Use SAP tools like the Proxy Test tool or SOAP UI to simulate messages with complete data.
  
  
  
  Adjust Interface or Mapping if Needed:
  
  If the business process allows, consider making some fields optional (not recommended unless business rules permit).
  Correct the mapping or interface design to ensure mandatory fields are always filled.
