Pastel Partner V18 - deleted invoices

SOLVED

Hi.
On Pastel Partner V18 - where can I see sales/customer invoices that were deleted? I know one is not supposed to delete invoices, but Pastel nevertheless allows you to delete it. We had a new staff member, who, when she invoiced wrong, she simply deleted the invoice, resulting in missing invoice numbers from doc number sequence. This creates an audit query off course. Where can I see those doc. numbers that were deleted?
I will greatly appreciate advice.
Thank you.
