right transmission medium and communication in output determination

Hello Gurus,

I defined a new output type for shipping, wrote a requirement, but I don't know which transmission medium should I define in the output type and the right communication definition in the condition records.

I need this output to execute a program that calls a "proxy to file" method (interface).

Each transmission medium I used caused me a dump, so eather the program the ABAPer gave me is wrong, or my definition is wrong.

Regards,

Daphna
