• What is the cause and solution for SAP error message WPRO_XI_PROXY003 - Mandatory field &1 is not filled ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WPRO_XI_PROXY003 Mandatory field &1 is not filled
  
  Cause:
  This error occurs when a mandatory field in the proxy message structure is not populated before sending the message. In SAP PI/PO (Process Integration/Process Orchestration) or SAP XI (Exchange Infrastructure), proxy interfaces define certain fields as mandatory. If these fields are left empty or not filled in the payload, the system raises this error to indicate that the message does not meet the required data completeness criteria.
  
  Explanation:
  
  The placeholder &1 in the message will be replaced by the name of the mandatory field that is missing.
  This typically happens during the runtime of a proxy message when the inbound or outbound proxy tries to send or process a message.
  The proxy runtime checks the message against the interface metadata (XSD or WSDL) and validates mandatory fields.
  If a mandatory field is empty or missing, the proxy runtime throws this error to prevent incomplete data from being processed or sent.
  
  
  Common Scenarios:
  
  The ABAP code or the sender system did not populate the mandatory field.
  Mapping or transformation logic removed or failed to populate the mandatory field.
  Incorrect interface configuration or mismatch between sender and receiver interface definitions.
  Data extraction or input errors in the source system.
  
  
  Solution:
  
  
  Identify the Missing Field:
  
  Check the error message details to find out which field (&1) is missing.
  Review the interface definition (WSDL/XSD) to confirm that the field is mandatory.
  
  
  
  Check the Data Source:
  
  Verify the source data or the ABAP code that populates the proxy message.
  Ensure that the mandatory field is correctly filled before sending the message.
  
  
  
  Review Mapping/Transformation:
  
  If there is any mapping or transformation step, check if the mandatory field is being removed or left empty.
  Adjust the mapping logic to ensure the mandatory field is populated.
  
  
  
  Debugging:
  
  Use transaction SXMB_MONI or SXI_MONITOR to monitor the message and check the payload.
  Use debugging tools in ABAP or PI/PO to trace where the field is lost or not set.
  
  
  
  Interface Consistency:
  
  Ensure that the sender and receiver interfaces are consistent and that the mandatory fields are correctly defined.
  If the interface was recently changed, confirm that all systems are updated accordingly.
  
  
  
  Testing:
  
  After corrections, test the message processing again to confirm the error is resolved.
