• What is the cause and solution for SAP error message WPRO_XI_PROXY201 - Bonus buy header data is missing ?

  The SAP error message:
  WPRO_XI_PROXY201: Bonus buy header data is missing
  
  Cause:
  This error typically occurs in SAP when processing a bonus buy or promotional order via the SAP XI/PI (Process Integration) proxy interface. The message indicates that the required header data for the bonus buy transaction is missing or not correctly passed in the proxy message.
  In other words, the inbound proxy or interface expects certain header information (such as order header details, customer info, or promotional header data) to be present in the XML payload or IDoc, but it is either absent or incomplete.
  Common causes include:
  
  Incorrect or incomplete data mapping in the middleware (SAP PI/XI).
  Missing mandatory fields in the source system or interface payload.
  Incorrect configuration of the proxy or interface.
  Data extraction or transformation errors before sending the message to SAP.
  
  
  Solution:
  
  
  Check the Interface Payload:
  
  Verify the XML or IDoc message sent to SAP.
  Ensure that all mandatory header fields related to the bonus buy are present and correctly populated.
  Typical header fields might include order number, customer ID, promotion ID, validity dates, etc.
  
  
  
  Review Mapping and Middleware Configuration:
  
  Check the SAP PI/XI mapping steps to ensure header data is correctly mapped from the source system to the SAP proxy.
  Validate that no fields are dropped or incorrectly transformed.
  
  
  
  Validate Proxy and Interface Configuration:
  
  Confirm that the proxy interface is correctly configured to receive and process the bonus buy header data.
  Check the proxy metadata and ensure it matches the expected structure.
  
  
  
  Check Source System Data:
  
  Ensure that the source system (e.g., CRM, external order system) is sending complete and correct data.
  If the data is missing upstream, correct it at the source.
  
  
  
  Debugging in SAP:
  
  Use transaction SXMB_MONI (PI Monitoring) to check the message processing status.
  Use transaction SPROXY to check the proxy interface and metadata.
  If you have access, debug the inbound proxy to see where the header data is expected and why it is missing.
  
  
  
  Consult SAP Notes:
  
  Search SAP Support Portal for notes related to WPRO_XI_PROXY201 or bonus buy header data issues.
  Sometimes SAP releases patches or notes for known interface issues.
