Stock Available to Promise Release

Currently the reservation is performed by adding reserved quantities on quants, which is fine as long as the reservation is made right after the order confirmation. This way, the first arrived, first served principle is always applied. But if you release warehouse operations in a chosen order (through deliver round for example), then you need to be sure the reservations are made in respect to the first arrived first served principle and not driven by the order you choose to release your operations.

Allow each delivery move to mark a quantity as virtually reserved. Simple rule would be first ordered, first served. More complex rules could be implemented.

When the reservation of a picking move occurs, the quantity that is reserved is then based on the quantity that was promised to the customer (available to promise):

  • The moves can be reserved in any order, the right quantity is always reserved
  • The removal strategy is computed only when the reservation occurs. If you reserve order 2 before order 1 (because you have/want to deliver order 2) you can apply correctly fifo/fefo.
    • For instance order 1 must be delivered in 1 month, order 2 must be delivered now.
    • Virtually lock quantities to be able to serve order 1
    • Reserve remaining quantity for order 2 and apply fefo
  • Allow to limit the promised quantity in time. If a customer orders now for a planned delivery in 2 months, then allow to not lock this quantity as virtually reserved
  • Allow to perform reservations jointly with your delivery rounds planning. Reserve only the quants you planned to deliver.

When move qty is not completely satisfied on release, the remaining qty is split and attached to a new picking that can be released later.

Important: if the "Stock reservation horizon" is set, the qty is calculated on moves which have an expected date not beyond $today + $horizon (in days).


This is an alpha version, the data model and design can change at any time without warning. Only for development or testing purpose, do not use in production. More details on development status

Table of contents


In Inventory > Configuration > Routes, activate the option "Release based on Available to Promise" on the routes where you want to use the feature.

To modify the horizon go to "Inventory > Settings" and change "Stock reservation horizon".


When an outgoing transfer would generate chained moves, it will not. The chained moves need to be released manually. To do so, open "Inventory > Operations > Stock Allocation", select the moves to release and use "action > Release Stock Move". A move can be released only if the available to promise quantity is greater than zero. This quantity is computed as the product's virtual quantity minus the previous moves in the list (previous being defined by the field "Priority Date").
