We expect to use sales prepayments, set to 100%, and also invoice rounding of 1.00 for each sales invoice.
the prepayments should not affect the fx gains and losses account, especially when the LCY currency is used.
If I use invoice rounding of 0.01, with prepaymet amount set to 100%, the sales prepayments entries are posting correctly to GL accounts. Unfortunately we need to implement sales invoice rounding of 1.00
When I use invoice rounding of 1.00, the system will request I add the LCY currency to the currency table when I set the customer to 100% prepayment, and this will result in entries being posted to FX gains and losses account which is wrong.
