It has been possible for some time now to use ABAP RFC function modules in CAP applications. This provides a convenient way to integrate with existing ABAP functionality without needing to create a custom OData API when a standard one is unavailable. By leveraging standard RFC function modules, you can avoid unnecessary custom development in your backend system.
In this blog post, I’ll show you how to configure Build Code and VSCode to use ABAP RFC function modules.
However, use this approach carefully and only when necessary. I still recommend using APIs whenever possible—resorting to RFCs should be your last option.
