hi,

I want to apply tax global.Means not in product order line.

Tax apply on untaxed  amount of sales order.

Example:

• I have one sales order SO001

• In order line   5 Product is available which price different.

• not total of 5 product i want to apply tax instead of order line.

• Then Final Figure Should come with untaxed amount + taxed = Total amount

• 
  

Is it Possible?
