Configuring BO Sp4.1 on Sybase

Dear Friends,

Need your help and guidance to resolve this issue i am facing.

Scenario..

I am trying to install BO SP4.1 and the database i am chosen is Sybase ASE 15.7, Operating system is Win 2012 64 bit Version.

Also my BW Netweaver ABAP stack is also on this system and databse for that is also Syabse ASE 15.7. But for BOBJ i have installed seperate database with different SID, So i think that should conflict with BW database Kindly suggest if i am on the right track.

Next

1. I have attached a screen shot in which i am struggling to by pass this screen although the user i am using can connect through CMD but when when i     put this user on BO installation its gives error can i use sa user over here instead of other user. Screen says sa so i was using both but what is right approch.

Actually i create a new login in the BO Database and assign sa roles to it should be OK right please suggest...
