Labor-Burden in Last Cost

Is there anyway to verify the Labor and Burden Costs that show up in
the last cost field.

I am trying to do it by looking at the Production Detail Report and
the $ amount of Labor and Burden charged to the job and I am coming up
with different #'s then the system is.

Thanks
Marty

PS..the job isn't complete yet but we have received parts from this
job into our inventory and thats the # I am using to divide into the
Labor and Burden charged to the job so far.
