Hello

We are using B2B feature for our ATO items (assemble to order / configured item). Until recently (before 21D), if we had stock on-hand for an item flagged as "B2B enabled = yes" but no reservation between the on-hand stock and the sales order line, the system would not pick the item.

Now, if I have a SO line with 20 qty requested for a B2B item, 10 qty reserved for this SO line, 7 qty on-hand available (not reserved), the system will create a pick with the 10 qty reserved + an additional line of 7 qty for a total of 17 qty.
