hi, i would like to ask if this plugin is able to help in this situation:
1) customer orders some products on store that either contains (pre-order / backorders)
2) order goes thru and this order is marked as Pending (because waiting for stock to arrive)
3) there's maybe 10 other customers who make the same order, eg: total backorders for Product A is 100pcs
4) while i created a Purchase Order (in ATUM) to order Product A 100pcs
5) however, due to urgency, supplier managed to send 50pcs first, while 50pcs coming in another batch of shipment
6) i marked in Purchase Order (in ATUM) that i received partial stock of 50pcs
7) **it will auto-mark those orders that contains those orders that contains Product A with "Waiting for Shipment" or "Processing" by the order date and time, sorted by which order is the oldest, be fulfilled with the stock first (until 50pcs is fulfilled), aka FIFO.
