Fatal error in calling R3 RFC function.

[NickSYYang]

Hi, ALL:

I add my client's R3 server into my EP as an system object (connection test succeed.).

Then I drag & drop an RFC function from 'Find data service' into my VC iView.

But storyboard always empty, after that I check log from Visual Administrator.

I got following error message.

<b>[code]failed JCO execute function; stack trace: com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: User EPO.ACL has no RFC authorization for function group RFC2 .[/code]</b>

Any advice would be very appreciate, thanks.

Please grant RFC2 authorization to your user into R/3. Always see transaction code ST22 to know ABAP dump and transaction code su53 to check authorization.

Hi, Nitin:

Thanks for your useful information. Actually, my client give me another ID/PWD which have enough rights to call RFC/BAPI function on R3. So, I can continue my development.
