Calling two diferent R3 systems for same RFC

Hello Everybody,

My scenario is:

I have one RFC in two different systems. this is the same RFC available on two systems. I want to call this RFC from the Web dynpro application. System will be determined at runtime to call this RFC.

If user selects System XYZ then using hte same RFC model, RFC should be executed on XYZ. If user selects System ABC then using hte same RFC model, RFC should be executed on ABC.

Can we achieve this using single RFC model in one web dynpro application?

If not, then can we create two RFC models containing same RFC?

Regards,
