  SAP Error Message:
  WPRO_XI_PROXY203 Bonus buy type is missing
  
  Cause:
  This error typically occurs in SAP when a required field related to the "Bonus buy type" is missing or not populated in the data being processed, especially in scenarios involving integration with SAP XI/PI (Process Integration) or when handling proxy messages related to promotional or bonus buy transactions.
  
  The "Bonus buy type" is a mandatory field expected by the system to identify the type of bonus or promotional purchase.
  The error indicates that the inbound proxy message or the data payload does not contain this required field.
  It can happen due to incorrect or incomplete data mapping in the interface, missing master data configuration, or an issue in the sending system not providing this information.
  
  
  Solution:
  
  
  Check the Incoming Data:
  
  Verify the payload of the proxy message to ensure that the "Bonus buy type" field is present and correctly populated.
  If the data is coming from an external system, confirm that the sending system is sending this field.
  
  
  
  Review Interface Mapping:
  
  In SAP PI/XI, check the mapping between the source and target structures.
  Ensure that the "Bonus buy type" is mapped correctly and not filtered out or left blank.
  
  
  
  Master Data Configuration:
  
  Confirm that the "Bonus buy type" exists in the SAP system and is properly configured.
  Check relevant customizing or master data tables where bonus buy types are maintained.
  
  
  
  Proxy and Interface Configuration:
  
  Check the proxy object definition to ensure the field is mandatory and correctly defined.
  If the field is optional in the interface but mandatory in the backend, adjust accordingly.
