How to Make Discount Item Report

How to make Discount Item Report based on V4 Tutorial DISCOUNT- Any Item - ASK Fix Percent?

After i search on Forum, i get this report but how to solve it
[#Discount:1,1,1,1,1,2,2, 3]
>Ticket No|Date|Time|Table|Name|Discount|[C]Discount Amount|[C]Discounted Price
{REPORT ORDER DETAILS:T.TicketNumber,T.Date,T.Time,EN.Tables,O.MenuItemName,OT.Discount Percent,OTP.Discount Percent, ON.TotalPrice:(OT=Discount Percent)}

why OTP. Discount Percent, not show discount amount, just show 0

any body help me for this issue
