A Credit Note based on a Progressive Invoice is used when previously invoiced progress (under a project or contract) needs to be reversed or adjusted. This can occur due to:
Overstated progress in a project
Revisions in certified quantities or values
Errors in the original progressive invoice
Agreed deductions after invoice issuance
A credit note can be created manually through the sales documents screen:
Sales → Sales Documents → Credit Notes.
