Invoice Discount is only factored in the Final Invoice and not in Prepayment Invoices. Current workaround is to enter the Invoice Discount as Line Discount. However, in most cases, the invoice discount is granted to round off the final sales figure Eg. total sales order value is $500,100 and salesperson grant $100 invoice discount to round the value to $100.
In such cases, it is not practical for users to input Line Discount line by line, especially if the volume is large - 100+ lines per each sales order.

Can Microsoft consider to include Invoice Discount% for calculating prepayment invoices?
