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).

Hi Tiwari,can you answer my latest comment. Thank you

So let’s say the original invoice has the following information:
Doc. Number: 100
Items:
Product x , quantity 10
Product y, quantity 20

When customer returns 3 items of product x and 2 items of product y , then I will report the following:
Doc number: 100-CN-01
items:
Product x , quantity 3
Product y, quantity 2

If later on, thw customer adds 4 items of product z, then I will repprt debit note as follows:
Doc number: 100-DN-01
items:
Product z , quantity 4

Ofcours I will include VAT in all documents.
Please advise if the above example was
written correctly. Thank you
