In sales order lines, the user can enter negative value in the discount percentage field in the line to upscale the price.

For example if the unit price is 100 and they enter -50 in the discount percentage field, the net amount value will be 150.

However, when creating a new trade agreement journal from the sales and marketing module, we cannot create a Line discount (Sales) line and specify that the discount % on Discount1 or Discount2 as negative value, the user receives the following warning:

"Field 'Discount percentage can only contain positive numbers."

It would be great to have a feature to enable the user to enter negative values in trade agreements for sales order, as it is allowed to add negative value in sales order lines.
