Order or invoicing unit.
The product can have five packaging units available:

Four packaging units entered in the grid of the product-units record.
One packing unit linked to the supplier (product-supplier record) and two purchase units:

One purchase unit linked to the master product.
One purchase unit linked to the product-supplier. In order entry, this unit is suggested by default if a product-supplier record exists. Otherwise, the purchase unit of the product record is suggested by default.

Only the packing or purchase units previously mentioned can be selected.

Depending on the purchase order transaction used, you can access (or not) the order unit. If the transaction does not authorize the entry of the order unit, it is initialized to the purchase unit defined for the supplier or to the purchase unit of the product if this does not exist.

In the case of an order arising from a requirement, the unit suggested by default is the purchase unit of the supplier for the product or the purchase unit of the product.

It is possible to modify the order unit proposed. From the Actions icon, you can view the list of units including: the stock unit, the product packing units, the product purchase unit and the different units suggested for the supplier.

When the order line originates from a direct order, the order unit is determined based on the value of the POHCTMPUU - Direct order in purchase unit parameter (ACH chapter, ORD group).

In the buyer plan, if the supplier is modified and its units are different from those of the former supplier, a message is displayed suggesting to order in stock unit in order to avoid any price list inconsistency and keep a coherent order unit for the supplier. If you answer Yes, the order unit is readjusted into stock unit. If you answer No, the quantities are readjusted keeping the supplier's units.

Inter-company specificities: In the case of an inter-company or inter-site order, the unit is checked to ensure that a correspondence exists in the Sales module. Otherwise, a blocking control prohibits the entry of this unit.
