You can use the CheckBill of Materials option to see if you have sufficient quantities of subcomponents for a Bill of Materials (BOM) to make up the required quantity of the finished item. It picks up any products where the Free Stock + On Order is less than the quantity required.

If there are insufficient quantities, the Chk BOM option can be used to automatically create a purchase order for the required quantities.

1. Go to Products and services then select Check bill of materials.
2. Click the Product code drop-down and select the required product.
3. Enter the quantity required, Qty Req, then click Check.
   
   You may receive one of the following messages:
   

   Quantity already in Stock	This message appears if there is sufficient quantity of free stock for the finished product.
   Quantity not in stock = (number) This quantity is available through the stock transfer	This message appears when there is insufficient free stock of the finished product, but there are enough subcomponents to make up the required quantity. You should use the Transfer option to make up the required quantity of the finished product.
   Quantity not in stock = (number) The current Quantity available to make up = (number)	This message appears when there is insufficient free stock of the finished product and not enough subcomponents to make up the shortfall. The subcomponents that need to be ordered appear in the window. If there is insufficient free stock the Qty to Order column is either the Re-order Quantity from the product record or the amount of the shortfall, whichever is greater, you can use this to create a purchase order.
