We have a whole bunch of RFC-interfaces from various systems into SAP that we want to convert into OData services, but...
Should we choose OData V2 or OData V4?
The obvious choice would be to start using the latest version right from the beginning - but as I understand the early (7.50 SP04) implementation of OData V4 had some limitations/constraints compared to V2. However I don't have a clear understanding of what this would mean for us - how critical those limitations are - and if we should start with V2 instead and then make the switch to V4 later on.
What would you recommend?
We have only just recently upgraded to 7.50 SP06 and I don't think we will do another upgrade anytime soon.
Bonus question: Is there - or will there be - some kind of tool to convert a service from V2 to V4?
