Compute invoice amount (line and total)

Question

Hi,

in an invoice, when you change the discount on a line, amount of the line and of the invoice is automatically recalculated.

I would like to do the same by clicking on a button that i've added in the invoice form view.
Probably by calling the same function than the automatic way.

Is anybody know how to do that?

Vincent

I don't know the version, but in your button click you can add some custom code like in V13,
for line in self.move_line_ids:
line._onchange_price_subtotal()
