We cannot help you until you share your code, specially constraint.
the code has grown quite large but ill try to compress:
class Order(models.Model):
order_line = fields.One2Many('order.line', ...
cost_center_line = fields.One2Many('cost_center_line', ...
amount_total = fields.Monetary(store=True, compute='_compute_amount')
amount_cost_center = fields.Monetary(store=True, compute='_compute_cost_center_amount')
@api.depends('order_line.price_total')
def _compute_amount(self):
for rec in self:
amount = 0.0
for line in rec.order_line:
amount += line.price_total
rec.amount_total = amount
@api.depends('cost_center_line.amount')
def _compute_cost_center_amount(self):
for rec in self:
amount = 0.0
for line in rec.cost_center_line:
amount += line.amount
rec.amount_cost_center = amount
@api.constrains('amount_total','amount_cost_center')
def _constrains_amount(self):
for rec in self:
if rec.amount_total != rec.amount.cost_center:
raise ValidationError('...')
