Small user mapping problem!!!

Hi "helpers",

I've made a user mapping to be able to display a BW report in an iview of the portal but it still asks me a login and password to display it.

I think I've configured everything correctly. This is what I've done:

- I've created a system because the one that was needed was for client 800 and I needed client 100. So I've made a copy of the "client 800" system and changed it as 100.

- Then I've created the alias for my new system.

- After I've mapped my portal user with the login and passeword I use to display the report.

This is right/enough?

I'm wondering if it doesn't take a little bit of time to the portal to take care of those changements???

Thanks for your advices.
