How to add labour cost in Item Production

Dear Friends,

In one FG Production I required to add Labour cost in that FG production cost.

for that i have used following process :

Create Labour as non inventory item with issue method 'Backflush' and  Costing method 'Standard'.

In FG BOM add that Labour with quantity and Price.

But after Production we get FG cost is only SUM of Row material cost without Labour Cost.

Is it possible to add that Labour Cost in FG Production cost?
