My apologies all. I could not get chance earlier to come on board & say "Thanks you" This board has been so helpful & you guys are very generous with your time & efforts to reply & provide guidance. Thanks a million again !!!!

Thanks a lot for solution. It perfectly worked.

Thanks again for your help Yashwanth, Yes error is quite new & I have raised SR with Oracle. Internal authentication with SUPERVISOR is working fine. I can connect to Master as well as Work repo using SUPERVISOR.

Thanks a lot for your kind reply. 1. Actually name "Dev-WorkRepository" is bit misleading as I connect to both Work & Master Repository with same name, all I do is change Radio button. 2. I tried again with making sure Master Repository is selected but same error. 3. Reviewing document you provided. Just FYI this external…

Yes first & second both steps are visible. Error happens only after I hit Finish button

Thanks Srini. Forgot to mention that we have 11g (11.1.1.7.0).
