Hi, i made custom on Items doctype to set Item Tax per item like this.
Example
Item 003 set PPN as Selling Transaction
Server Side
Set condition if type of transacation is Selling or Buying and get Tax Template
Script Side
Problem
On Purchase Order Document = Buying Transaction i call item 003 that i set sellling item tax but on items at field Item Tax Template = PPN (which is Selling Tax) that i want is Item Tax Template = Empty because is not Selling transaction
Thanks & Regards.
