Field help (VATRULP)

The tax calculation rule is defined at this level for the footer element.
It is important to remind here the definition rule of the applicable tax rate. The tax rate is usually defined by crossing a tax rule applied to the supplier (and which can be modified during the various transactions in the various documents) and a tax level possibly applied to the invoicing element or to the invoice lines.
 Refer to the documentation on the tax rates for further details.

It is possible to choose between two rules to calculate the taxes of the footer elements.
A footer element not allocated on the invoice lines will necessarily have a fixed-rate type tax rule.
A footer element allocated on the lines can have a tax rule with a fixed rate or a product rate.

• Product rate: it amounts to applying to the footer the same level of tax as the product defined at the level of the invoice lines. In this way, this product tax level crossed with the tax rule defined for the supplier gives the tax rate that will be applied to the footer element. If the purchase invoice is composed of several lines where the products have different tax levels, the footer will be subjected to different tax rates proportionally to the Ex-tax amount of the total for the lines with the same tax level.
  Depending on the automatic journal associated with the invoice type, it is possible to use either a dedicated account for this invoicing element or directly impact the revenue accounts. If a dedicated account is used, it uses the first tax code associated with the invoice tax grid,
• Fixed rate: means to apply a single tax rate for the footer element as a whole. The Tax level must then be specified. This level will be used to determine the rate to be applied according to the rule specified at the level of the Supplier BP or the invoice.
