How to do a credit memo process correctly.

[Jose Daniel Castellanos]

Hello everyone, I hope you are very well.
I'm a new user in iDempiere and I am trying to understand how to generate a credit memo from an invoice.
Is it necessary to reverse that invoice and then create the credit note?

I'm very confused and I would appreciate if someone could help me with a guide or a step-by-step process, since I have not been able to find a good tutorial on the internet that explains it.
Thank you very much for your attention, I hope you can help me.

Hi Nicolas.

I really appreciate the time you took to respond.
Regarding your answer, I know that I have to do that after the Invoice is complete.
My question was more focused on how to effectively see a cancellation in the value of the Lines of the credit memo, or a global discount or a single product or service.
