# Subcontract Generate Lot

## Overview
This Odoo 19 module provides automated lot/serial number generation specifically for subcontracting receipts. It isolates the subcontracting automation feature from legacy modules, ensuring compatibility with Odoo 19's native "Lot Sequence per Product" functionality.

## Features
- **Auto-Generate Lots**: Automatically generates lot/serial numbers for subcontract receipt moves based on the product's configured sequence.
- **Validation Check**: Prevents lot generation if the linked Subcontract Manufacturing Order is cancelled, alerting the user to potential data inconsistency.
- **Wizard Support**: Includes a "Generate Subcontract Lots" wizard for manual control and batch generation.
- **Validation Hook**: Automatically triggers lot generation when validating a subcontracting receipt (Stock Picking).
- **Native Compatibility**: Uses Odoo 19's standard `lot_sequence_id` on the product template, ensuring no conflict with standard features.

## Prerequisites
- **Odoo Version**: 19.0
- **Dependencies**:
    - `stock`
    - `mrp`
    - `mrp_subcontracting`

## Installation
1.  Place the module in your custom addons path.
2.  Update the **App List** in Odoo.
3.  Install **Subcontract Generate Lot**.
4.  **Important**: If you are migrating from `product_lot_sequence_per_product`, you MUST uninstall that module after installing this one to prevent conflicts.

## Usage
1.  **Configure Product**:
    - Go to a Product form -> **Inventory** tab.
    - Set **Tracking** to 'By Lots' or 'By Unique Serial Number'.
    - Configure the **Lot/Serial Numbers Sequence** (Standard Odoo field).
2.  **Subcontract Receipt**:
    - Create a Purchase Order for a subcontracted product.
    - Confirm the PO to create a Receipt (Stock Picking).
    - On the Receipt, use the **Auto Generate Lots** button or validate the transfer to trigger generation.
