Configuring Tax Rate Calculation in AP Invoice

Summary:

Currently, the tax rate in the AP Invoice is determined based on the Product Category field. However, we would like to change this to use the Tax Classification field instead.

Could you advise where we can configure this?

From our review of the setup, we are unsure whether we need to modify the Tax Determining Factors and Tax Rules settings or make changes elsewhere.

Our current setup on Tax Rules as image below.
