A	Select the item number for the item you want to adjust. To do this, click in the Item Number column, press tab, and then select the item from the list that appears.
B	If you hold inventory at multiple locations, select the location where the item is stored. This field only appears if you have more than one location. For more information, see ‘Create Item Kits’.
C	Type the quantity by which you want to increase or decrease the quantity held. Only type the quantity variation. Type the quantity in inventory units, not buying or selling units. If you enter a positive number, that number is added to your on-hand inventory. If you enter a negative number, that number is subtracted from your on-hand inventory.
D	The average cost of the item appears by default. The average cost is normally calculated as the total cost of the item divided by the number of units on hand, but if these are new items, type their purchase cost.
E	The Amount field displays the quantity multiplied by the unit cost. If you change it, the unit cost is recalculated automatically.
F	The allocation account is usually a cost of sales or expense account.
