I have an invoice where I want to give client some item as discount
But I still want to reflect the item and value in the amount field as negative value, and to be rested from Total.
for that have a check-box to set the record as is-rested to do the discount.
Here is an example.
check-box price qty Amount
false 1. item 1 $50.0 1 -$50.00 C
true 2. item 2 $100.0 1 $100.00
true 3. item 3 $100.0 1 $100.00
----------------------------total $200.00
How can this be accomplished?
