Steps to reproduce the bug:
- Create a storable product “P1”
- Create a purchase order with 3 unit of “P1”
- Confirm the PO and receive the delivery
- Go to inventory > operation > Inventory Adjustments
- Select the “quant” of “P1”:
- quantity = 3
- inventory_quantity = 0
- Click on “Apply”
- Apply the wizard
Problem:
The quantity is updated to 0
When the `_apply_inventory` function is called, a move is created and
validated to ensure that the quantity matches its corresponding
`inventory_quantity`:
https://github.com/odoo/odoo/blob/15.0/addons/stock/models/stock_quant.py#L606-L611
`inventory_diff_quantity` is equal to -3 in this case, since it's the
result of computing `inventory_quantity` - `quantity`, which is (0 - 3).
Since we add a minus sign to `inventory_diff_quantity`, the final result
becomes `3`.
Afterward, we call the `_update_available_quantity` function with a
minus sign as well, so the value becomes -3:
https://github.com/odoo/odoo/blob/e1cea2640fc064a56b0dba4f79e6b8a91a48b4fc/addons/stock/models/stock_move_line.py#L307
As a result, when we add `quant.quantity`, which is 3, the final result
becomes 0 (3 - 3):
https://github.com/odoo/odoo/blob/9d34c72b2c7bc187c5aac771e9e8cbddd7ead5f2/addons/stock/models/stock_quant.py#L635
Solution:
If no inventory_quantity set, ignore the apply of inventory for this
quant.
