Hi Nikki
Just see the example:
Debit:( GI+Activity) at Standard price 600
Credit at (GR value) at standard price 500
Variance between at standard price 100
So..in this case Act cost with variance = (500+100) = 600 matching with cost booked but all value at standard price
But after CKMLCP run all this standard price will converted to actual price at single/multilevel price calculation considering various PRD generated and calculate PUP which is the right actual cost.
I think now I have put some light on the issue
