The name of the file received by the AS4 component.
If a file name is included in the AS4 request's message headers, it will be written to this context property.
Note: this value is also placed in the File.ReceivedFileName and the FTP.ReceivedFileName context properties. This is to ensure compatibility with other connectors that poll those context properties to fill out macros such as %SourceFileName%.
This property is not available in the Sender.
