Stock Picking Putaway Recompute

This module lets warehouse users refresh the destination locations of an ongoing transfer when the putaway configuration has changed after the transfer was created.

• A new option 'Allow to recompute putaways' appears on the operation type form (Inventory > Configuration > Operation Types). It must be enabled for the transfer type before the button becomes available.
• On a transfer form, a 'Recompute Putaways' button is shown when the transfer is ready (state assigned), its operation type allows it, and the transfer has not been printed yet.
• On the detailed operations list, a small button next to the destination location lets users recompute the destination for a single operation line, provided the line has not been picked yet.
• The recomputation re-applies the putaway rules to the selected operations and updates their destination locations.
• A safety check prevents recomputing when only part of the move lines sharing the same destination package are selected; in that case an error message is shown.
• The buttons are only visible to users with the multi-locations setting enabled.

The module extends stock.picking, stock.move.line and stock.picking.type and adds buttons to the transfer form, the detailed operations list and the operation type form.
