Inventory consumption entry in tally

Pass the purchase and payment entry for solid spice as usual. For grinding expenses ledger, enable the option ‘inventories values are effected’ and tag the inventory item against the amount. Afterwards pass a stock journal.
.
# Suppose you purchase 100 kgs of solid haldi @ Rs. 50/kg & spent Rs. 1000 for grinding.
.
# To know the effective cost/kg, grinding expenses shall be added to the cost as it is being incurred in bringing the spice to its present condition. Now effective rate will be Rs. 60/kg.
.
# Then pass a stock journal. In source column enter 100 in qty. and 6000 in amount. In destination column enter 90 in qty and 6000 in amount. Let rate be calculated automatically.
.
# After this you’ll get effective rate of Rs. 66.67 for 90 kgs available, using FIFO method.

BUT HOW REMAINING 10 % WILL GET EFFECTED ?

DO WE HAVE TO PASS ANY JOURNAL ENTRIES FOR THE SAME AS IT 

IS NORMAL LOSS WITH AMOUNT .

PLEASE CLARIFY IT
