Hi
We are planning to build OData services from SAP using Netweaver Gateway for consumption in a mobile app and I'm having some very basic questions.
When I tried looking that the most recommended deployment approach for NW Gateway, I got some contradictory results.
There's an old blog that quotes (and commented by SAP) that SAP recommends the cetral hub instance and a subsequent blog that says there's no clear indication on the right architectural option while there's an old sdn doc (stamped approved and all) from SAP which says the most recommended option is the embedded approach.
Since its been quite a while, is there any clear stance that SAP is taking now on the best deployment options or is it still based on the enterprise's existing landscape, security etc?
- If NW Gateway server is installed on ECC as an add-on in the embedded approach, is it then possible to retrieve data from other SAP systems( eg: BW, POS-DM) through (RFC connections?) and build once single OData service?
- SAP says it recommends OData Channel approach for all NW Gateway development. Does OData Channel development differ based on which deployment option you chose? It mentions backend OData Channel and hub OData Channel. How different are they?
Thanks!
