• What is the cause and solution for SAP error message WPRO_XI_PROXY205 - Bonus Buy identifier is missing ?

  The SAP error message WPRO_XI_PROXY205: Bonus Buy identifier is missing typically occurs in the context of SAP CRM or SAP Marketing scenarios where a proxy interface is used to communicate bonus or promotional data, and a required identifier related to the "Bonus Buy" is not provided or is missing in the payload.
  
  Cause
  
  The error indicates that the Bonus Buy identifier (a key field that uniquely identifies a bonus or promotional offer) is missing in the data being sent or processed.
  This identifier is mandatory for the processing of bonus buy or promotional transactions.
  It usually happens during the inbound or outbound proxy communication where the XML or data structure does not contain the required field.
  Possible reasons:
  
  The source system or middleware did not populate the Bonus Buy identifier.
  The mapping or data transformation step missed this field.
  The data model or interface definition expects this field but it was not provided.
  Custom enhancements or user exits that manipulate the data might have removed or failed to set this field.
  
  
  
  
  Solution
  
  
  Check the Interface Definition:
  
  Verify the proxy interface (e.g., in SAP PI/PO or SAP CRM) to confirm that the Bonus Buy identifier is a mandatory field.
  Review the XML schema or data structure for the proxy message.
  
  
  
  Validate the Source Data:
  
  Ensure that the source system or the sending application populates the Bonus Buy identifier correctly.
  Check the data in the inbound message or payload to confirm the presence of this field.
  
  
  
  Review Mapping and Transformation:
  
  If middleware (like SAP PI/PO) is used, check the mapping steps to ensure the Bonus Buy identifier is correctly mapped from source to target.
  Correct any missing or incorrect mapping.
  
  
  
  Debug or Trace the Proxy Processing:
  
  Use transaction SXMB_MONI (for PI/PO) or SLG1 (application log) to trace the message processing.
  Check for any errors or warnings related to missing fields.
  
  
  
  Check Custom Code or Enhancements:
  
  If there are user exits, BAdIs, or enhancements involved in the proxy processing, verify that they do not remove or fail to set the Bonus Buy identifier.
  
  
  
  Correct the Data and Reprocess:
  
  Once the missing identifier is added, reprocess the message.
