Calculate Tax only based on specific Tax Calculation Code selected in Invoice Line

Hi All,

  My name is Cecifia. Currently I am facing some issue in EBTax especially when apply the Tax at Invoice Line (Payables: Invoice Workbench). I would like to ask if anyone know what is setup that affects the tax calculation in invoice lines.

For example, for country United States, there have 3 different tax regimes (99AP UK VAT-99AP, GBTax – GB-VAT & UK VAT RB – UK VAT).

How to only calculate the Tax Classification Code (e.g STD) which under Tax Regimes (e.g 99AP UK VAT-99AP) at the invoice line without involve others 2 taxes (e.g GBTax – GB-VAT & UK VAT RB – UK VAT) in the application that also belong to United States country?
