Multiple ECC with multiple clients to single client of Gateway
We have implemented SAP Fiori as central hub model with multiple ECCs connecting to one client of Fiori - Let us say 300. However, one company in our group has two clients on its ECC system - let us say 400 and 500. We would like to connect them to our client 300 of Fiori. From the current discussions on the forums and documents it seems that we have to create another client on Fiori - let us say 310.
Is there a way to not have to create another client on Fiori? What is the most elegant architecture solution for our landscape?
