Credit & debit note basics

Hi,

Maybe my question is basic but its important.
Let us say that I reported an invoice with some line items ( products). Later, I made some changes to the quantities for one of the line items basically reduced the quantity of one of the products . Now, to report a credit note, should I send only the adjusted line item with the new quantity or I should send all line items even the old ones basically overwriting the referenced invoice? Similarly the debit note what should I do? Please help.

Thank you.

@mortadha Credit Note and Debit Note should contain only the items that are returned / added (for the delta).
