Before S/4HANA was available I do the below to create custom oData service and custom Fiori app for Launchpad:
- In back-end ECC ABAP server I use t-code SEGW to create custom oData service.
- In Front-end NW 7.4 server I register the back-end custom oData service using t-code /n/IWFND/MAINT_SERVICE
- The custom oData service is used for a custom developed Fiori app in front-end NW.
How the custom oData service development will be in S/4HANA ?
Will it be .xsodata using the XS app in HANA data base and using Eclipse ?
or there will be ECC ABAP back-end server using HANA DB insted of DB6 ?
