It is not possible to unreserve more products of ...

have in stock

This article is from odoo forum .

If you have a problem as me , it was working to me.

Do several step as below :

1.debug mode

2.technical/server actions

3.create

4.action name: e.g. fix unreserved qty

5.model: ir.actions.server  (Server Action)

6.action to do: "execute python code"

7.copy/paste the fix underneath the pre-existing code

  ===========================

quants = env['stock.quant'].search([])
move_line_ids = []
warning = ''
for quant in quants:
move_lines = env["stock.move.line"].search([
('product_id', '=', quant.product_id.id),
('location_id', '=', quant.location_id.id),
('lot_id', '=', quant.lot_id.id),
('package_id', '=', quant.package_id.id),
('owner_id', '=', quant.owner_id.id),
('product_qty', '!=', 0)
])
move_line_ids += move_lines.ids
reserved_on_move_lines = sum(move_lines.mapped('product_qty'))
move_line_str = str.join(', ', [str(move_line_id) for move_line_id in move_lines.ids])
if quant.location_id.should_bypass_reservation():
# If a quant is in a location that should bypass the reservation, its `reserved_quantity` field
# should be 0.
if quant.reserved_quantity != 0:
quant.write({'reserved_quantity': 0})
else:
# If a quant is in a reservable location, its `reserved_quantity` should be exactly the sum
# of the `product_qty` of all the partially_available / assigned move lines with the same
# characteristics.
if quant.reserved_quantity == 0:
if move_lines:
move_lines.with_context(bypass_reservation_update=True).write({'product_uom_qty': 0})
elif quant.reserved_quantity < 0:
quant.write({'reserved_quantity': 0})

move_lines = env['stock.move.line'].search([

])
move_lines_to_unreserve = []
for move_line in move_lines:
if not move_line.location_id.should_bypass_reservation():
move_lines_to_unreserve.append(move_line.id)
if len(move_lines_to_unreserve) > 1:
env.cr.execute(""" UPDATE stock_move_line SET product_uom_qty = 0, product_qty = 0 WHERE id in %s ;""" % (tuple(move_lines_to_unreserve), ))
elif len(move_lines_to_unreserve) == 1:
env.cr.execute(""" UPDATE stock_move_line SET product_uom_qty = 0, product_qty = 0 WHERE id = %s ;""" % (move_lines_to_unreserve[0]))

 ============================

8."save" 

9."create contextual action"

10.refresh page

11.action/fix "fix unreserved qty" / Run

12.wait for it to load 

13."remove contextual action"

14.action/delete
