The problem arises when a user creates a backorder for a MO after registering overconsumption of some components through the simplified view. The quantities of the components of the new backordered MO are then wrong. Components that were over consumed in the first MO will have smaller quantities in the new MO, the difference being the amount over consumed. This problem does not appear in the case of the Tablet View where a proper recalculation of quantities is done. closes odoo/odoo#64911 Signed-off-by: Arnold Moyaux <amoyaux@users.noreply.github.com>
