Execution order on inherited functions
I want to know if there is a specific order of execution on inherited functions. I know that If you add dependencies on your module your function is going to be called first and then the super, but, my question is that if I can set the order of execution when addons are not related between them.
For example, on sales.order:
If I want to override product_id_change() I can create a module, and set the dependency to sales module. But What happens with product_id_change that is on product_visible_discount. I'm not going to set the dependency of my module to product_visible_discount. But how could I be sure that my code is going to be called first before product_visible_discount, or the opposite, if I want my function to be called after this, how could I set this?
