Required feature to reserve stock automatically as per stock availability. i.e. Suppose we have 5 pcs. of a barcode and we have an order of 7 pcs of that barcode. When we click on "reserve stock" it do not reserve the stock due to stock unavailability.
It can be done by going into reservation and fill barcode qty. manually but as our one order contains almost 100 line items this functionality do not works.
