When entering an Extended Price in any marketing documents, the system should auto calculate the discount following any change to the Ext. Price field. This way it will keep Ext. Price = Qty * (Unit Price - Discount) consistent. Right now, you are able to enter Qty 2, Unit Price $10 and no discount. Then change the Ext. Price to $2000 (for e.g), the order will stay as 2 x $50 = $2000. This is an issue when creating reports as well since it can be very inaccurate to use Ext Price due to that issue.
