Issue while Maintaining Dimension Members

Hi Gurus,

I have upgraded my MS Office from 2010 to 2013. Below is the screen shot of my MS office version.

Now issue is I am not able to maintain dimension members. Every time we click on a "Maintain Dimension Members" nothing happens. It was working fine while I had 2010. We are at the latest service pack (BPC MS10.0 SP16).

Not able to figure out what is the issue as I don't get any errors.

Any Idea?

Thanks,

Charly
