RFC function modules


in UX4.0 these function modules are RFC enabled:

used by Designer:

used by Server


In order to maximize security, we only have authorized RFC access for the marked (*) server function modules.

Is it correct to assume that the other ones are not to be used by newly developed apps anymore??

Best regards,


For running an app you will need the following 6:



All of them are used by  class   /NEPTUNE/CL_NAD_SERVER.

Hi Kay,

your assumption is correct if and only if you are not going to develop new apps using the  Frontend / Backend Split  setup option  (which makes use of RFC calls).

Kind regards,


I assume that as a developer, the FMs used by the Designer are necessary.

But is authorizing users for the marked FMs sufficient for running an app in a productive environment?


Ok, thanks for the clarification!

Best regards,
