# Stock Restrict Source Location
This module implements strict location filtering for Stock moves and Manufacturing Orders based on the configuration set in the Operation Type.
This module implements targeted location filtering for Stock Moves and Manufacturing Orders, ensuring users can only pick components and stock from authorized source locations defined in the Operation Type.
## Features
- **UI-Level Restriction**: Restricts the "Pick From" location selection in both standard Transfers and MO "Detailed Operations" dialogs.
- **Background Reservation Restriction**: Overrides the reservation engine (`_get_gather_domain`) to ensure auto-pick (Check Availability) only pulls stock from authorized locations.
- **MO Support**: Specifically handles Manufacturing Orders by injecting the `active_mo_id` and `active_move_id` into the context.
- **Frontend Patch**: Includes a JavaScript patch (`stock_move_line_x2_many_field_patch.js`) to ensure picking type context is maintained during frontend searches.
- **Surgical UI Filtering**: Restricts the "Pick From" (Quant) and "Lot/Serial Number" (Lot) selection in both standard Transfers and MO "Detailed Operations" dialogs.
- **Backend Sync Safety**: Specifically designed to bypass restrictions for background Odoo operations (reservation, unreservation, record-linking) to prevent "Missing Product" validation errors.
- **Context-Aware MO Support**: Handles the complex Manufacturing Order "Components" view by injecting the correct picking type and source location into the search context.
- **Frontend Patch**: Includes a JavaScript patch to ensure location context is correctly passed from the UI to the backend search methods.
## Dependencies
- `stock`
- `mrp`
- `stock_picking_type_m2m` (Used to retrieve the list of allowed locations)
- `stock_picking_type_m2m` (Used to configure the list of allowed locations on the Operation Type)
## Usage
1. Configure **Allowed Source Locations** on your Operation Type (e.g., Manufacturing).
2. Create an MO or Transfer using that Operation Type.
3. Both manual selection and the "Check Availability" button will now be restricted to precisely the locations you defined.
1. **Configure**: On a **Picking Type** (Operation Type), set the **Allowed Source Locations** (M2M field).
2. **Operation**: Create an MO or Transfer using that Picking Type.
3. **Lot Selection**: When a user clicks to select a Lot or a Quant in the UI, the list will be filtered to only show availability from the allowed locations.
4. **Backend**: Odoo's internal "Check Availability" and "Save" processes will still function normally, ensuring that reservations are linked correctly to existing stock.
## Technical Implementation (V19)
- Overrides `StockQuant` and `StockLot` `_search` methods with a **UI-only bypass**.
- Only restricts queries that include UI indicators (like `params`, `search_view_ref`, or `bin_size`).
- Bypasses restrictions for the system user (`uid=False`) and searches by direct ID to maintain ORM integrity.
