Prepayment document is already cleared

What causes this issue?

The change you have entered and wish to make to the invoice document
necessitates the cancellation of a prepayment document.
The supplier line item of the document has already been cleared on the
supplier payables account. It is therefore no longer possible to cancel
the prepayment document.
