Discount amount in Sales Order

Hi, i noticed that the Discount amount is missing variable in the existing ones, it have the percentage but there is no amount (as much as i can see)…

is it there but am not seeing it or if its not there how can i add it?

When you make “Item price” for Respective Item then only “Discount” field will be appear on
sales order form.

@shraddha isnt there a way to get the amount instead of percentage?
