Field help (BPEVACBPS)

The supplier tax rule by default is stored in the Supplier record.
In the case of a multi-companies management, the same supplier can be subject to a different tax rule according to the company they deal with.
Use this field to enter exceptions and to set the supplier tax rule by company.
Only the tax rules in phase with the legislation and the group of the indicated company can be entered.

The general principles linked to the multi-legislation setup are detailed here.
