Newby Stupid question

Okay, so this is probably me just being stupid and not understanding.

I have a dimensional database that I populated using SSIS. One fact table has about 78,000 records. When I build a cube on top of the database, I get no results for the measures on the fact table.

What would be a typical reason for something like this occurring?

Thanks
JimProbably you didn't design the Dimension Usage.
