Display R3 main screen

Hello all.

I need to create an iView that will display R3 main screen.

I tried to create a SAP Transaction iView using transaction name SESSION_MANAGER but when I run it I get the following error message:

"The Internet Transaction Server could not start the transaction "SESSION_MANAGER" because of the following error: ."

Does any one have any idea how I can create this iView?

We are using portal EP6.

Thanks,

Gil
