Suppliers ship what they have. Half your order turns up today, the rest next week on a different invoice that still quotes your original PO number. Data Entry Pro keeps track of that for you, so back orders don't sit in MechanicDesk as pending forever.
Part deliveries are where manual entry goes wrong most often. Someone receives the whole PO by mistake, or receives the right quantities but forgets the back order, or the second invoice gets entered against the original PO that was already received. The result is stock levels and costs you can't trust.
The first invoice only covers some of the PO. With Back Orders On, Data Entry Pro receives exactly the quantities delivered.
MechanicDesk creates the back order PO for the rest (for PO 1844 that's 1844/1), and Data Entry Pro bills what arrived.
The next invoice arrives quoting the original PO number. Data Entry Pro sees that PO was already received and goes to the open back order instead.
If that delivery is still short, MechanicDesk creates the next back order (1844/2) and the cycle continues until the order is complete.

Back Orders On
Receive what was delivered and create back orders for the rest.
Back Orders Off
If an invoice doesn't cover the whole PO, only prices are synced and no bill is created, so nothing is received by mistake.
No, that's the normal case. Data Entry Pro follows the original PO to its open back order (/1, /2 …) and bills against that.
Then an invoice that doesn't cover the whole PO only updates prices on the PO and doesn't create a bill. It's the cautious option if you'd rather receive part deliveries yourself.
If the PO has already been received and nothing is left open, Data Entry Pro stops with a clear message and changes nothing, rather than editing a received PO.
No. MechanicDesk creates the back order PO when the partial receipt is processed. Data Entry Pro just receives the right quantities and keeps track of which PO is open.
