Cash discount-relevant amount is zero; check entry

What causes this issue?

You have entered a cash discount for a line item for which the cash
discount base amount is zero.

System Response

You receive a warning. If you entered a cash discount percentage rate,
no cash discount is displayed because the base amount is zero.
However, this cash discount is taken into account if you explicitly
predefined a cash discount amount. The cash discount percentage rate
cannot be calculated in this case and, therefore, is not displayed.

How to fix this error?

Check your entry and make an adjustment if you entered a cash discount
by mistake.
