Ok, I have been trying to learn ODATA from past one week and I have understood that we can make use of Odata by RFC/BOR and DDIC Structures.
By making use of DDIC structures/tables we can code in the respective methods(by redifining) to perform CRUD operations and by RFC well I haven't learned it precisely, I followed the exact same steps mentioned by Mr Volker Drees but I'm getting error 500.
FYI the link is Step-by-step guide to build an OData Service based on RFCs – Part 2
There's not much data available other than that for working with RFC/BOR.. I mean there needs to be much simpler demonstration with a very simple RFC.
Which makes me think why odata and why not webservices.. What advantages Odata has over webservices.
Also, if it's not too much to ask please try to address my issue by giving a simpler Odata example using an single RFC, you know just give an input and get an output kinda example.
