Hi,

Odoo v14. 

I would like to know how I can link manually a sale order to an invoice.

This is the problem I have:

Customer ordered and paid goods, goods were delivered. 

Customer returns all the goods and requests new ones in different amounts.

We make return of all goods and accept them in warehouse. All goods are returned.

I adapted the invoice to the correct amounts. I than cancelled the sales order and placed it back to concept and adapted the amounts but when I confirm it shows already part as delivered and I can not change those quantities to 0 . Strange as a full return on that sales order has been executed.

My solution would be to cancel the entire sales order , make a new sales order and connect that one to the existing invoice. But I don't know how to do that.

Hopefully someone can help me out.
