It is possible to add more than one discount to Sales Proposal Slips and Sales Contracts. To do so, "Additional Discount" option located in F9 menu of the slip is used. You can apply 5 discounts to the operation in line. When "Apply to All Lines" option is selected, additional discounts are applied to all lines in the slip. When this option is selected, these additional discounts are listed right under each relevant line.
Lines for which discounts are applied in order can be closed and listed in a single line. All lines to which discount is applied are closed and displayed in a single line by Alt + F7 combination.
No discount information is displayed in lines closed as bold. However, when the cursor is on Amount or Amount in FC columns, a tip box opens displaying information about the sub lines. Tip boxes displayed on Amount - Amount in FC columns will show line information of the relevant line only. When re-pressed on Alt + F7 combination, all closed lines will open. When pressed on F7 on any line of the slip, the relevant line closes while the other lines remain open.
