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.
• 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.

  • stock
  • mrp
