Stock Rule Reserve Max Quantity
This module extends the functionality of chained (pull) stock reservation to support the reservation of the total quantity brought by the done and pregenerated chained move lines. By default, the reservation on each step of the chain is limited to the need. If you pick more than the need, with this module the chained moves will reserve the total picked quantity.
This operation will only apply when the available quantity exceeds the demanded quantity and the stock rule linked to the stock move has the field Reserve Max Quantity activated.
This module is not needed if you use chained pickings and the creation of those is placed when the a picking is validated.
auto_awesome What this module does
AI-generated from the code · Odoo 18.0Adds a "Reserve Max Quantity" option on stock rules so that, when more goods are picked than needed, the next steps of the chain reserve the full picked quantity instead of only the required amount.
This module adds a single checkbox, "Reserve Max Quantity", on the stock rule form (the rules that drive how Odoo moves and reserves stock between locations). It appears in the same group as the other rule propagation settings.
When that checkbox is ticked on a rule, any stock move created by that rule changes how it reserves stock: instead of reserving only the quantity demanded by the next step, it looks at the quantity already done on the previous moves of the chain and reserves up to that amount, as long as stock is available. In practice, if a warehouse worker picks more than the planned quantity, the following step of the chain will reserve the extra picked quantity too, so the surplus is not left unreserved.
The behaviour only kicks in when the rule has the option enabled and when there is enough available stock; otherwise the standard reservation logic applies. It affects stock moves and stock rules in the Inventory app. No new menus, reports or scheduled jobs are added.
