Structure of a Purchase Order
The structure of a purchase order within the Lawson Purchase Order application has two basic components: a purchase order header and purchase order lines. When you create a purchase order, you enter the header and then assign lines to the header. The lines contain the specific item information for the order.
Purchase Order header
The information in the purchase order header (PO header) pertains to the entire purchase order document. In the header you enter the company, buyer, vendor, ship to location, and delivery date. After you create the header, each line that you add is assigned to the header information you specified.
Purchase Order line
A purchase order line (PO line) contains order information about a specific item. Each line must contain the item number, quantity, unit of measure, and unit cost. In addition, you have the option to add a delivery date and ship to location to a particular line if it is different than what you specified in the header.
Each purchase order line (PO line) can also contain more detailed information about a particular item. Such detail can include item size and color, as well as line-specific cost information such as line tax and other add-on costs.
After you have created the purchase order and added it to the Purchase Order application, you can add other header and line options such as add-on cost spread.
