Managing Internal Purchase Orders

A purchase order with a supplier defined with supplier type 7-'Internal' in 'Internal supplier' in 'Supplier. Open' (CRS620) is an internal purchase order. Internal purchase orders can be created manually using 'Purchase Order. Open' (PPS200), through the Purchase Order (PO) batch entry or by releasing a planned order.

If a planned purchase order is created with an internal supplier and a supplying warehouse can be found, a material reservation is created to represent the planned Customer Order (CO) issue (see also Defining Internal Sales and Material Planning for Internal Sales).

Once an internal PO is printed and is set to status 20, an internal customer order is automatically created in the selling facility, using the CO batch entry. Each purchase order number is always connected to exactly one customer order number. Two planned purchase orders whose warehouses represent different customer numbers can never end up on the same purchase order.

'Active Supply Chain. Display' (MWS150) is used to view the relation between the customer order and purchase order.

After a purchase order has been printed, changes to existing order lines or header will not automatically update the customer order, even if the purchase order is re-printed. However, if a new line is added to the purchase order and printed, a new line will be added to the customer order. If a purchase order line has reached status 20, it may no longer be deleted.
