Locations and picking helpers

Odoo’s stock reservation logic treats every internal location the same way once a removal strategy is chosen: it does not let a warehouse restrict a given transfer (or sales order) to a subset of shelves, it has no quick hierarchical/type filter on the locations list, and its built-in removal strategies (FIFO, LIFO, closest location, FEFO) cannot be reordered by an arbitrary, manually-ranked priority. This page documents four small eYssen modules that close those gaps: two that let an operation type, transfer or sales order be pinned to specific storage categories for picking, one that adds a search panel to the locations list, and one that adds a rank-based removal priority strategy and reflects it on the delivery report.

Key features

Restricting picking to specific storage categories

The eyssen_stock_location_pickable module adds an Allow Pick from Storage Categories field (technical name allow_pick_categories, a many2many to stock.storage.category) on the operation type, and a matching field on the transfer itself.

• On the Operation Type form it acts as the default: any storage category can be added, and it is left empty by default (no restriction).

• On the Transfer form the field is computed from the operation type when the transfer is created, but stays editable (readonly=False) as long as the transfer is not Done or Cancelled, so a specific transfer can deviate from its operation type’s default.

When the field holds one or more categories, reservation only considers quants sitting in a location whose Storage Category is one of the selected categories, or in a location that has no storage category set at all — locations with a different storage category are excluded. This filter is applied by overriding stock.quant._get_gather_domain() and stock.quant._get_quants_by_products_locations(), and is only active when the allow_pick_categories context key is set.

Important

The restriction is a pure reservation filter — it does not add a “pickable” flag on the location or storage category themselves. A location is eligible simply because its storage category is in the allowed list (or it has none).

To make sure the filter applies no matter which code path triggers reservation — a manual Check Availability, a backorder, a chained move, or manual quantity entry on the operations tab — stock.move overrides _action_assign(), _get_available_quantity() and _set_quantity_done_prepare_vals() to inject the transfer’s allow_pick_categories into the context before delegating to the standard logic. The value also survives backorder creation: the picking’s copy_data() is overridden to copy allow_pick_categories onto the backorder copy.

Propagating the restriction from sale orders

The eyssen_stock_location_pickable_sale module extends eyssen_stock_location_pickable to the sales flow. It adds the same Allow Pick from Storage Categories field on the Sales Order, placed next to Warehouse in the shipping information, editable while the order is a Draft.

When the order is confirmed and a delivery is created, stock.move._get_new_picking_values() is overridden to copy the sales order’s allow_pick_categories onto the new delivery automatically — no manual step is needed on the transfer.

Quick location filtering with the search panel

The eyssen_stock_location_searchpanel module inherits the standard locations search view (stock.view_location_search) and adds a searchpanel with two facets:

• Location — a hierarchical filter (location_id) that lets you drill down the warehouse tree and filter the list to a parent location and its descendants; and

• Type — a multi-select filter on the location’s usage (Internal, Customer, Vendor, Inventory Loss, Production, Transit…) with a record count shown next to each option.

The panel appears automatically on any list that uses the standard locations search view — no configuration is required after installation.

Ranking locations for the removal strategy

The eyssen_stock_removal_priority module adds a new, custom removal strategy alongside Odoo’s built-in FIFO, LIFO, closest-location and FEFO strategies.

• A Removal Priority integer field (technical name removal_priority, default 1000) is added to Location and shown on both the location form (next to Removal Strategy) and the locations list view.

• A related, stored removal_priority field is added on stock.quant so each quant inherits its location’s rank.

• A new Priority removal method (product.removal record, method code priority) is registered, making it selectable anywhere a removal strategy is chosen — on a location’s Removal Strategy field or a product category’s Force Removal Strategy field.

When Priority is the active removal strategy for a product/location, stock.quant overrides _gather() so that eligible quants are sorted by ascending removal priority first, then by the location’s full name, then by quant ID — the same tie-breaking pattern Odoo already uses for the closest location strategy. A lower Removal Priority number is therefore picked before a higher one, letting you rank shelves explicitly (e.g. front-of-shelf bins at 10 vs. bulk overflow storage at 1000) instead of relying purely on stock age or physical distance.

Note

Quants without a lot are still always sorted after quants with a lot, matching standard Odoo behavior for all removal strategies.

The module also adjusts the Delivery Slip report (stock.report_picking): the operations table, which normally lists move lines sorted by source and destination location name, is re-sorted by the source location’s removal priority first, so the printed pick list reflects the same shelf order the reservation logic used.

Configuration

Storage-category picking restriction

1. Enable multi-location: Storage Categories and the Allow Pick from Storage Categories fields only matter once locations use a storage category, which requires the Storage Locations setting (group stock.group_stock_multi_locations).

2. Define storage categories and assign them to locations under Inventory ‣ Configuration ‣ Warehouse Management ‣ Storage Categories, then set each location’s Storage Category field.

3. Set a default restriction on an operation type under Inventory ‣ Configuration ‣ Operations Types ‣ (open a type) ‣ Allow Pick from Storage Categories.

4. Optionally override the restriction per transfer on the transfer form, or — with eyssen_stock_location_pickable_sale installed — per sales order in the shipping information before confirming the order.

Location search panel

No configuration is required. Once eyssen_stock_location_searchpanel is installed, the Location and Type facets appear on Inventory ‣ Configuration ‣ Locations.

Removal priority strategy

1. Rank your locations under Inventory ‣ Configuration ‣ Locations: open each location and set its Removal Priority (lower numbers are picked first; the default is 1000 for every location).

2. Activate the strategy either on the location itself (Removal Strategy field) or, to enforce it for every location holding a given product family, on the product category’s Force Removal Strategy field under Inventory ‣ Configuration ‣ Product Categories. In both cases select Priority.

Usage

To restrict a delivery type to a picking area:

1. Go to Inventory ‣ Configuration ‣ Operations Types and open the Delivery type used by the relevant warehouse.

2. In the Allow Pick from Storage Categories field, add the storage categories that are allowed to fulfil deliveries of this type (for example, only forward-pick shelves, excluding bulk reserve storage).

3. Confirm a sales order for a product stocked in both an allowed and a non-allowed location, and check the resulting delivery: Check Availability only reserves quants from the allowed storage categories (or from locations with no storage category at all).

4. If needed, open the delivery and adjust Allow Pick from Storage Categories directly on the transfer before it is done.

To rank shelves for the priority removal strategy:

1. Set a Removal Priority on each candidate location (lower = picked first).

2. Set the product’s category Force Removal Strategy to Priority.

3. Deliver the product and confirm that reservation — and the printed delivery slip — picks from the lowest-priority-number location first.

Tip

The locations search panel makes it fast to check this setup: filter the Locations list to Internal locations under the relevant warehouse and compare each location’s Removal Priority and Storage Category columns side by side.

Scope and modules

• eyssen_stock_location_pickable — the Allow Pick from Storage Categories field on operation types and transfers, and the reservation-time storage-category filter.

• eyssen_stock_location_pickable_sale — the same field on sales orders, propagated to the delivery automatically on confirmation.

• eyssen_stock_location_searchpanel — the Location and Type search panel on the locations list view.

• eyssen_stock_removal_priority — the Removal Priority field, the Priority removal strategy, and the priority-ordered delivery slip report.
