Can you revoke and delete a Service Entry that clearing document number?

[Former Member]

We received a credit memo against an invoice that was posted to a service entry. The invoice was paid and has a clearing document. The credit memo was posted but when we try to revoke and delete the SE, there is an error message: An invoice already exist for this service entry.

If already invoice is posted, then you've to reverse the invoice before revoke Service entry sheet.
