Romania e-Invoice System - Credit note and Correction Invoice Cases

What is the difference between a credit note and a correction invoice? As far as we understand, a credit note is the same as reference ordinary invoice but with correct information and negative amounts, after an ordinary (380)invoice received an error by the ANAF. Also, we can add a reference invoice number for tracking, is it enough right? Can we have to copy all information from the reference invoice or partial (which is incorrect) information enough?

Correction invoice needs to be created to make changes to the reference-ordinary(380) invoice upon request from the invoice recipient, right? This way we can add a reference invoice number, right? We can also create a negative amount. Can we have to copy all information from the reference invoice or partial (which is incorrect) information enough?

Thanks,
