R12: AR adjustments form - Tax amount is shown inclusive of the discount amount.

Hello,

In AR, certain customers are set up with early payment discount terms.

So if an invoice (£120  = 100 + 20% tax) was due on 30-May-2015 and customer pays before 25-May-2015, a 10% discount would be applied.

Customer decides to pay on 20-May-2015 so he/she will avail a discount of £12 (£10 + £2 vat)

Now when user goes into receipts > adjust > selects the line > (discount applied and amount discounted are populated) > adjustments -- there the discount line shows the amount that is tax inclusive. (one line for £12)

Is there a way i could split these in two different lines - a) Line discount amount for £10  and b) Line tax amount for £2??
