Dear sir, I want to add an option for print discount column in defaut tally sales invoice for both simple & comprehensive. And this option comes at invoice printing configuration level. IF DISCOUNT OPTION IS SET TO YES THEN DEFAULT SALES INVOICE PRINTOUT. AND IF DISCOUNT OPTION IS SET TO NO THEN RATES COME AFTER DISCOUNT. i.e. if i given rate 10000 & rate 2%=200 then there is rate is 9800 and no discount column is displayed or print. Thanx in advance.
