I already do this: I created the "Tax-rule 01" active on the B2C shop and the "Tax-rule 02" active on the B2B shop.
But, when a product is edited and updated on "All shop" mode, after clicking "Save" button, the "Tax-rule 02" disappear on the B2B shop and in its place, prestashop inserts a general "no tax" rule. Probably this happen because on "all shop" mode, the tax rule saved is "Tax-rule 01" that is no active on the B2B shop, so prestashop on B2b shop inserts a general "no tax" rule.
