Thanks Anatole ,

But its not the answer i am looking for i am asking to update the sales price of product in general information.

I have tried all of these but it always shows error. I have tried onchange, depends both but it not worked. If you have another idea please provide me. Thanks.  

Hello,

I am not sure if this work but you can try : 

configure_ok = fields.Boolean(string ="...", compute="_comp_total_price")

@api.depends('configure_ok')
def _comp_total_price(self):
    if self.configure_ok:
        self.total_price = # update price

You  can also look for @api.onchange to do what you want.

I hope it help, good luck !
