Total amount of the discount

Good morning and thank you very much to all the people who make this project possible.
First of all, I apologize for my English (thanks to GoogleTranslator :slight_smile: )
I need your help and wisdom because no matter how much I have searched and read, I cannot find a way to solve it.
I need the documents generated in the PDF (estimates, orders, invoices, etc.) to show me the total amount of the discount in €.
I need something like this:

Total discount: X€
Total TTC: X€
VAT 21%: X€
Total: €X

I hope you can help.

Thank you.
