Backorder MO - Cancelled work order operations.

[stevencodelab]

When creating a backorder MO to fulfill the remaining quantities to produce, the new MO is created with cancelled operations. Instead, I would like for it to create the new backorder MO without cancelling those operations.

How to fix this issue ?

I already try to override the action_backorder function like this but still nothing happen
def action_backorder(self):
res = super(MrpProductionBackOrder, self).action_backorder()

    backorder_move_vals= []
    for move in self.move_finished_ids.filtered(lambda x: x.state not in('done', 'cancel')):
        if move.product_uom_qty:
            continue
        backorder_move_vals.append(move._prepare_move_copy_values(move.product_uom_qty))
    if backorder_move_vals:
        backorder_production = self.copy({
            'move_raw_ids': [],
            'move_finished_ids': backorder_move_vals,
            'backorder_id': self.id,
            'date_planned_start': False,
            'date_planned_finished': False,
            'state': 'draft',
            'workorder_ids':[],
            'move_dest_ids':[],
        })  
        backorder_production._onchange_move_raw()
        backorder_production.action_assign()
    return res
