Query builder for WTDocument

Hi,

I would like to create a report with the query builder tool (Windchill 10.1).

The request should display a specific type of Wtdocument and the size of the file on the primary content for each document.

I would like also to define a date range.

The result we are expecting is : the liste of a type of Wtdocument created on a specific period, and for each the size of the file on the primary content

I don't find the attribute on the Wtdocument Table for the "size" or the "file size", also I don't find the attribute to select a specific type of Wtdocument.

Thanks if someone could help me.
