  Cause
  This error occurs when a mandatory field in the proxy message structure is not filled 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 null during runtime, the system raises this error to indicate that the message does not comply with the interface contract.
  Common scenarios causing this error:
  
  The ABAP proxy or Java proxy is called without populating all required fields.
  Mapping or data transformation logic does not fill mandatory fields.
  Incorrect or incomplete data passed from the sender system.
  Custom code or user-exits that inadvertently clear mandatory fields.
