Types of Purchase Order -
There are 6 Purchase order types:
The first Purchase order type is the journal. This type is used as a draft. It does not affect stock quantities and does not generate any item transactions and the quantity on the order line will not be considered in the Master scheduler. It can't be posted
EXAMPLE: A purchase order of the type Journal can be used when importing data by batch; in this manner, the purchase order can be reviewed and evaluated without affecting inventory, on-order, or other numbers.
This kind of purchase order is used if the vendor has not yet committed to fulfilling the order if the company has not confirmed the purchase order. Quotation type generates an issue lot with the type Quotation in the inventory and optionally in the Master scheduler.
Unlike the Journal type, the Quotation makes an entry in the inventory transaction table. Making this transaction is what enables Microsoft Dynamics AX to use this information for Master scheduling purposes.
This kind of purchase order is used for repeated purchases of the same goods or services. When a packing slip is updated, Microsoft Dynamics AX generates a receipt. When the invoice is updated for the receipt, a new packing slip or invoice entry can be updated for the same purchase line immediately or at some future date. The order will never be at an Invoiced status only Open or Received.
This type is used when you return goods to the vendor. A Return Merchandise Authorization (RMA) number supplied by the vendor is required when entering this kind of order
This kind of purchase order is used if there is a contract with the vendor and you want to order from the contract. Typically, a company uses blanket orders to receive better pricing conditions as the blanket order quantity is bigger than on single purchase orders. You can create a Release order to release, order, and invoice items until the contract is fulfilled. Blanket orders do not affect stock quantities, do not generate item transactions, and are not included in Master scheduling. Release orders, issued from Blanket orders, do affect all the above.
