How to fix this error?

If the manual billing has already been included in a print document,
you must execute an invoicing reversal of the print document before you
can execute a billing reversal.
If the invoicing document cannot or should not be reversed for other
reasons, you can correct the manual document by entering a new manual
billing.
If the manual billing document was not yet invoiced, you can delete it
in manual billing.
