TAX Categories
These are the TAX or VAT categories used in the alpha360 projects.
For simple Taxes or Vat you select TAX Calculation=Normal and fill in the 3 TAX% columns.
So for TAX NORMAL we have <Active = true>,<TAX Calculation = Normal >, (Default) TAX%=24%, Party with Reduced % TAXEs=9% and Parties configured as TAX Collector(s) with TAX Collector % =0.
A developer can of course use other TAX Calculations [like code or WEBServices] to return the TAXES%, but he must first code them.
Take a look at BP_Product_TAXes_Retrieve where you can find and edit the TAX% calculation.
