We use vertex to determine tax rates. We want to create a tax code e.g. I2 that will always return full tax rate for all state regardless of tax drivers that are being passed to Vertex. I create a tax code I2 copying I1 and in Vertex mapped to tax category TPP/Goods as this category is being accessed by Vertex tax engine first and it is linked to the full tax rate for all states. But I am not getting full tax rate in SAP. Any idea on how to solve this in vertex?
