Enter the first component in the Item Number column of the first line item in the scrolling list. The name of the item will be displayed automatically in the Name column, and the average cost per unit will be displayed in the Unit Cost column.
Enter the quantity by which you want the component to be reduced in the Quantity column. (Remember, since you’re reducing the quantity of the component, you should enter this quantity as a negative number.)
The Amount column automatically displayed the amount by which the total value of the component will be reduced when you record this transaction. You can change this amount, if you wish; however, keep in mind that the unit cost of the component will change to reflect the change you made.
Repeat the previous three steps for each component that’s used to build the finished item. When you’re finished entering components, proceed to the next step.
