In order to take advantage of allowing partial deliveries, it is necessary to defint the number of partial deliveries allowed. If you leave the Partial deliveries per item blank, you should populate the field below it “Max Partial Deliveries” with a 2 or higher. If the Max partial deliveries is left blank, or 1, you are telling the system that the first delivery for that line item is all of the shipments allowed. If you use 2, it will allow a partial and one additional shipment, which needs to be the remainder of the backorders material. If the second shipment is made for less than the remaining quantity, you will be blocked from shipping the balance.
The field is available in the customer master and will copy into the sales document. It is also in the sales document.
If you get the error and need to ship more, the Max deliveries can be updated in the order and the delivery will be created.
We use this field with custom coding in the user exit to insure we manage shipping expenses.
