Installed new version on 1.4.10. VAT is calculated on the price before the discount. In many countries, VAT is only due on the discounted product price. Is there a setting that I overlooked to achieve this ?

Hello,
After skipping several updates(i altered the code to much) i installed the last version(1.4.9)
I noticed that the item totals are wrong calculated when adding discount.
The tax amount is not correct.
Discussed it already a long time ago in this post: bug
see attached screenshot.
it must be:
item= 10
discount= 2-
subtotal = 8
tax 21% = 1,68+
Total = 9,68

I think you mean the discount for each item in invoice/quote. For invoices you must change following lines in application/modules/invoices/models/mdl_item_amounts.php :
$item_subtotal = $item->item_quantity * $item->item_price;
//$item_tax_total = $item_subtotal * ($item->item_tax_rate_percent / 100);
$item_discount_total = $item->item_discount_amount * $item->item_quantity;
$item_tax_total = ($item_subtotal - $item_discount_total) * ($item->item_tax_rate_percent / 100);
$item_total = $item_sub…
Suppose we add 10 items for 10 euro each, total 100 euros (no item tax in this example). Then we need to make a discount of 10 euros (per invoice not per item), so the total goes to 90. And then we need to add the invoice tax, for example 23%.
In such a case the formula would be: 10 x 10 = 100 - 10 (inv. discount) = 90 + 23% = 110,7
As it is now, IP calculates the invoice discount like this:
10 x 10 = 100 + 23% = 123 - 10 (inv. discount) = 113
Is there an option to calculate the discount bef…
