Stock Account Product Run FIFO Hook

Beta License: LGPL-3 OCA/stock-logistics-workflow Translate me on Weblate Try me on Runboat

This module adds hook points in the FIFO valuation process to add more flexibility in the information that is stored and processed during FIFO candidate calculations.

In Odoo 19, the valuation logic has shifted from stock.valuation.layer to stock.move. This module provides extension points for custom modules to:

  • Access FIFO candidate move information during valuation
  • Enrich stock moves with custom candidate data
  • Control standard price update logic during FIFO operations

Usage

  1. Add dependency of this module to your custom module:

    "depends": ["stock_account_product_run_fifo_hook"],

  2. Inherit from product.product in your custom module

  3. Override the hook methods to add custom logic:

    • _run_fifo_prepare_candidate_update(candidate_move, qty_taken, value_taken, valued_move=None) — Called for each FIFO candidate when it is consumed.

      • candidate_move: The FIFO source move being consumed
      • qty_taken: Quantity consumed from this candidate
      • value_taken: Value consumed from this candidate
      • valued_move: (obtained via context) The stock move being valued that is consuming this candidate

      Use it to capture exact qty/value taken, create usage records, or track valuation relationships between moves.

When valued_move is Passed to Context

The valued_move is passed to context when an outgoing stock move calls _set_value() for FIFO costing:

# In stock.move._set_value() for FIFO moves:
for move in fifo_moves:
    super(StockMove, move.with_context(valued_move=move))._set_value(
        correction_quantity=correction_quantity
    )

This happens when:

  1. An outgoing stock move (customer delivery, internal transfer, etc.) is being valued
  2. The product uses FIFO costing method
  3. The system needs to consume FIFO candidates to determine the move’s valuation

During this process:

  • _run_fifo() is called to calculate the unit cost
  • For each FIFO candidate consumed, _run_fifo_prepare_candidate_update() hook is called
  • The valued_move (the move being valued) is available in context
  • You can use it to link the candidate to the move being valued
