Mapping tax and account depending of the product

[sebastienbeau]

Is your feature request related to a problem?

When selling in Europe (or only in France but with some special dom-tom case), you need to apply local tax when reaching a certain amount. And sometime you need to map the tax (and also the account) depending of the product.

For example you sell products A and B with the tax 20% in France
But you need to sell it with a tax 13% for product A and 16% for product B in some fiscal position.

Right now it's impossible to do it

Describe the solution you'd like

I would like to introduce a new module account_fiscal_product_rule

That will have the following data models

class AccountFiscalPositionProductRule():

    name = fields.Char()
    fiscal_position_id = fields.Many2one("account.fiscal.position")
    product_tmpl_ids = fields.Many2many("product.template")
    category_ids = fields.Many2many("product.category")
    account_income_id = fields.Many2one("account.account")
    account_expense_id = fields.Many2one("account.account")
    seller_tax_ids = fields.Many2Many("account.tax")
    supplier_tax_ids = fields.Many2Many("account.tax")


class ProductCategory():

    fiscal_position_product_rule_ids = fields.Many2many("account.fiscal.position.product.rule")


class ProductTemplate():

    fiscal_position_product_rule_ids = fields.Many2many("account.fiscal.position.product.rule")

Then we can inherit the mapping logic (tax and account) to apply first this "specific rule" and if not rule match apply native rules

Describe alternatives you've considered

I had thinking about adding product_ids and category_ids on "account.fiscal.position.account" and "account.fiscal.position.tax". But the UI not really good for end user (too much configuration), and code will be not so easy to inherit.
