Hi Virinchy,
Thank for your information provided. I have Netweaver 7.4 java stack for portal and using OData on SMP v3.0 for iOS mobile, Since I'm doing native OData app for iOS mobile so the SAP Netweaver Gateway is required.
In my environment, Netweaver 7.4 is different machines than SAP R3. so is that consider the Front End system is different than Back End systems?
Can I say that the SAP Netweaver Gateway is possible to install in SAP R3?
Regards,
Choong
