Purchase Order functionality enables you to purchase new materials from suppliers, and so increase the inventory levels for materials in the warehouse.

Purchase Order statuses

- Not received: When you create a new Purchase Order and fill in the required information (see below), the Purchase Order is saved with "Not received" status. This means that the relevant items have not yet arrived in your warehouse and are in "Expected" status.

- Received: You should mark the Purchase Order as "Received" when the items have arrived in your warehouse. After marking a Purchase Order as "Received", the materials are added to the "In stock" quantity and the "Expected" quantity will be decreased. You can only receive all items on the Purchase Order, partial receiving is not yet supported.

You can revert a "Received" Purchase Order by changing the status back to "Not received". The relevant items will be eliminated from "In Stock" and added back to the "Expected" quantities in the "Inventory" list.

2. On a Manufacturing Order or in the "Inventory" list, click on the "+" button at the end of the line for a specific material to create a Purchase Order for the required material. Then fill in the missing fields in the pop-up window. This is a quick way to create POs for materials that are required by a Manufacturing Order or to re-establish optimal stock levels. To enter more details or edit the Purchase Order, navigate to the newly created PO in the "Buy" screen.

Each Purchase Order has a delivery status, which can be manually changed by the user. Statuses trigger specific changes in the inventory and also help to monitor and manage purchasing activities.
