Adding custom report as web part, but couldn't found it

Hello everyone

I’m trying to add a custom made report (on our own cubes) to the AX role center.

When I access the report in the browser of the AX machine, it works.

But when I try to add it as a web part in the role centers the browse window shows some strange directories. Don’t know from where they are (maybe it uses its own report server?).

Can someone help me adding this report as a web part? How can I get my report in this dialog box?
I’m searching on it for quite a long time now and any help is welcome :slight_smile:

Thanks in advance!
