Hello !  

I try my luck on the Forum :) I want to make an automatic formula that requires 4 amounts. I would like Odoo Studio to execute it itself on the "Contact" form of each "Company".

The amount 1 will retrieve the tax free base of the customer's invoices for the year.

The amount 2 should be entered by the user.

The Amount 3 is Amount1 - Amount2.

And the Amount 4 is Amount3 x 30%.

If there is the possibility of doing something but the user indicates things by hand then no problem or if we have to adapt then the same I am listening to your proposals.

Thanks a lot!
