Need to Report Quantity List by WBS

Hi,

I have tried using Cji1 listing the project actual cost line items by WBS but the list does not show quantities.  If I select a line item and go to Details I can then view a list with a column for quantities but the column is empty.  If I then double click on the line item I can view a detail screen showing the quantity to be zero for the line item.

Is there some sort of metrics that need to be assembled  to get the quantities? Maybe it was overlooked by our set up team.

If not, and the Work Breakdown Structure is designed to be used to show the quantity of work, then what should I do?

What T Code do I need to enter to display Stock Issue Material Quantity listed by WBS element.  Is this WBS BOM?

What T Code do I need to enter to display Labor Hour Quantity listed by WBS element?

Or what, if any, assembly changes need to be made so that all of our project mangers can see these very important  quantities in Cji1?

Thanks in advance.
