I have an analysis on a dashboard page.  It has worked great in the past.  But recently, the analysis does not display and I open the page. 

When I edit the dashboard page, I can see the analysis listed there.  However, there is a "!" icon next to the name.  When I hover over the icon, I see this message:

"Referenced Catalog Object Inaccessible".

I looked in the catalog and can clearly see that analysis listed.

I should also point out that this only occurs in our Test environment.  The Dev environment is working just fine.

Any suggestions as to what's causing this?  Or how to correct the problem?

Thanks!
