The name of the file received by the AS2 adapter.
If a file name is included in the AS2 request's message headers, it will be written to this context property.
This value is also placed in the File.ReceivedFileName and the FTP.ReceivedFileName context properties. This is to ensure compatibility with other adapters that poll those context properties when filling out macros such as %SourceFileName%.
This property is not available in the Sender.
