How to trigger EDI output type by logical system

Hi,

I am trying to propose a delivery output on delivery document based on logical system.

I have maintained partner profile by logical system. In the partner profile, i have given the delivery output type and the process code.

I have also maintained condition records for the delivery output.

I would like the system to propose the delivery output not by ship to party or sold to party but by the logical system.

Because i do not want to maintain 3000 customers in the partner profiles, instead trigger the output by logical system.

Please let me know, if anyone has gone thru this situation and resolved.

Thank you in advance.
