@ -5,6 +5,7 @@ This Odoo 19 module provides automated lot/serial number generation specifically
## 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.
