Selecting Excisable Item with Different Rates in Sale Invoice (Excise for Manufacturer)

When a same excisable item is purchased with different rate of duty or duty per unit from different suppliers, it is advised to select item multiple times in a sales invoice since the item has different rate of duty.

However, instead of selecting the item multiple times, if multiple supplier references are selected in Supplier Details screen of the sales invoice. The reference details are displayed incorrectly in Rule 11 invoice, and other reports including the returns. Additionally, the duty passed on under Total Duty and Duty Per unit will be incorrect. It captures only first purchase bill details. However, the assessable value appears correctly.
