Create an ODP - SAP Source System - BW 7.4 on Hana SPs09

hello experts, We have a bw 7.4 on hana SP09, and we've created a traditional source system to SAP ECC like the first picture below. is it possible to have two source system at the same time to point to SAP ECC and to have extractors running in both source system?. when I say two source system I'm refering to have a traditional source system to SAP ECC and a ODP source system to SAP ECC.

I've tried to create a new source system ODP - SAP, I've added the logical name before creating and using in the traditional source system to point to SAP ECC:

It said that already exists:

What do I have to do? New RFC?

Thanks.
