GNUCash 'Credit Notes

[Keith D. Fletcher]

Ladies, Gentlemen,

I am somewhat confused on the process of raising a credit note. From the various documentations that I have read it states that one should use an invoice to complete this task. I know that this may sound stupid but by raising another invoice are you not once again adding to your A/R? Do you enter negative values? If someone could please provide me with an idiot's guide that would be awesome.

Thank you for you time,
Gloriana

I have GNUCash 2.6.5
