OData Configuration Questions

Hello!

I am an SAP partner services advisor.

One of my partners is a mobile apps developer, and successfully carried out an implementation using their app, and ECC backend system and SAP Netweaver Gateway system 2.0. For the GTW configuration, they've followed the link below, and everything works fine (Gateway Configuration Guide --> OData Channel Configuration).

However their customer has the following questions related to the configuration and why it is technically required. Would you be able to provide some insight that I can provide back to the partner and their customer (questions below)?

Thanks!

   • IWCNT_WF
   • IWFND_CNP
2. What System Alisases are used, where and how?
3. Trusted connection: Should this be defined
   • from GW to SAP
   • SAP to GW
   • bi-directional

What is recommended and why?
