Hello all,
I want to create an application SAPUI5 which takes some inputs and gives output results. For that I have a function module with import and export parameters. I want to know the simplest way to create an OData model which uses this RFC (code below). For example- How many entities should I have? What CRUD functions do I have to define and things like that. Any kind of knowledge would be of great help as I am new to this.
FUNCTION zisu_ui5_change_objects.
