Can't see dates in details

Hi there.

I have created a bex query, where i show one characteristic (e.g. 0REBUILDING) with one date attribute (e.g. ZCREATEDATE).

In BEx i can see date ZCREATEDATE.

Then i've created universe in BO 3.1 based on this bex and created a report on universe.

In InfoView report i see business object 0REBUILDING (dimension) and ZCREATEDATE inside (detail). But i can't see any values in details. Tell me please, how can i see it, where is my mistake?

Thank u guys!
