Unable to import model in nwds through adaptive rfc2

Hi Everyone,

I am trying to import FM through adaptive rfc2 Model in NWDS 7.3

When I am trying to import, it is giving the error as shown below.

I have configured the destination under windows->Preferences->destination configurations->R/3 destination.

and also configured destinations for R3 in NWA as well, but still getting the same error.

couldn't able to go-ahead from here.

Thanks and Regards,

Naveen
