Duplicate Transaction from UI - List of fields which are duplicated or not

Summary:

What are the fields which are copied and not copied when "duplicating" (from UI) an invoice/ a credit note?

Content (please ensure you mask any confidential information):

We are creating some transactions by duplicating already created transactions. We search for the invoice/ the credit note to be duplicated and, then, we click on Actions> Duplicate. Is there a note that describes/lists:

• the fields which are copied and not copied using this feature?
• the accounting determination using this feature?
• the setting that would possibly allow copying or not some fields?

NB:

• it looks like "Comments" and "Special Instructions" are never copied
