It is possible within the Backstore app to quickly check for the missing quantities at the document. If the stock availability is not enough to complete this order, it is easy to immediately create a purchase or the manufacturing order that will contain the missing quantities.
To check the availability select the Stock availability option within the options menu. The item availability screen appears.
Within this menu we may create the purchase for the single item, create the purchase for the all items of the same vendor. We can also create a manufacturing order to produce the missing quantities.
