  The SAP error message /AIF/MES401 Must define raw structure for interface &1/&2/&3 typically occurs in the context of the Application Interface Framework (AIF) when there is a missing or improperly defined raw structure for a specific interface. This error indicates that the system cannot find the necessary data structure that is required for processing the interface.
  Cause:
  
  Missing Raw Structure: The raw structure for the specified interface has not been defined in the system.
  Incorrect Configuration: The interface configuration may be incomplete or incorrect, leading to the system not being able to locate the required raw structure.
  Transport Issues: If the interface was recently transported from another system, the raw structure may not have been included in the transport request.
