Quick Purchase order

This module adds a button on the purchase order form, next to the order lines, called "Add from supplier's product list". It is visible while the order is still in Draft or Sent status. Clicking it opens a product list screen where you can enter quantities for several products in one go and add them all to the order.

The product list shows the product name, the quantity to process, the unit of measure, the seller price, the quantity on hand and the incoming quantity. Each row also has an Open button to view the product. The list is editable directly, so you can type quantities quickly.

Two filters help you find the right products: one shows only products already on the current order, and one shows only products supplied by the supplier of the current purchase order. The seller price is calculated automatically from the supplier's price list, converted to the order currency when needed.

The module also adds a safety rule: if a product already appears on more than one line of the same purchase order, an error message is shown, because mass addition expects only one line per product. Access rights for editing products in this screen are taken from purchase order lines, so users who can edit purchase orders can use the mass addition screen.
