How to connect ABAP proxy to two different XIs

Hi, everyone.

I want to know there is a way to connect ECC to two different XIs using ABAP proxy.

As I know, it is much easier to make scenario with RFC or IDoc sender

but in our case we have to use ABAP proxy and must send to two XIs

So, according to the plant type in the record, data should be splitted to each XIs.

And I wonder I should use logical port for each XI.

Does anyone have a experience to implement this kind of scenario?

Then Pls show me the guide how to implement.

Very Urgent.

Thanks.
