• What is the cause and solution for SAP error message WPRO_XI_PROXY032 - Field &1 must not be filled ?

  SAP Error Message:
  
  WPRO_XI_PROXY032 Field &1 must not be filled
  
  Cause:
  This error occurs during the processing of a proxy message in SAP PI/PO or SAP Process Integration when a particular field in the inbound or outbound proxy message is filled, but according to the proxy's definition or the message mapping, this field should be empty (not filled).
  Typically, this happens because:
  
  The proxy interface or the message type expects the field to be empty (e.g., a field defined as optional or empty in the message structure).
  The sender system or the mapping incorrectly populates a field that should remain empty.
  The proxy runtime validation detects that a field which must not be filled contains data, violating the message contract.
  
  
  Solution:
  
  
  Check the Proxy Interface Definition:
  
  Review the proxy interface (in the Enterprise Services Repository or Integration Builder) to identify the field mentioned in the error (&1 will be replaced by the actual field name).
  Confirm whether the field is defined as optional or should be empty.
  
  
  
  Check the Message Mapping:
  
  Verify if the mapping incorrectly populates this field.
  Adjust the mapping to ensure that the field is not filled when it should be empty.
  
  
  
  Check the Sender System:
  
  If the proxy is inbound, check the sender system or the source message to ensure it does not send data in this field.
  If the sender system cannot be changed, consider adjusting the mapping or implementing a filter to clear this field before the proxy processing.
  
  
  
  Adjust the Proxy or Message Type (if applicable):
  
  If the business requirement has changed and the field should be filled, update the proxy interface and regenerate the proxy classes accordingly.
  Otherwise, ensure the field remains empty as per the interface contract.
  
  
  
  Testing:
  
  After corrections, test the message processing again to confirm the error no longer occurs.
  
  
  
  
  Related Information:
  
  This error is related to strict message validation in SAP PI/PO proxy runtime.
