I would like to ask about “What is the correct way to fix Sales order which has already been invoiced”?
I have a case like, sales order has been invoiced. And at that moment users realise that the sales price was wrong. And what is the correct approached to correct the invoiced sales order? Because it has affected several account (Sales revenue, Inventory, etc)
Should i just using another methods which is more steps:
Create a new line with negative (-) quantity, Direct delivery > Product receipt PO > it will then auto generate negative (-) invoices values. Then create a new line with positive (+) quantity, Direct delivery > Product receipt PO > It will generated the final correct invoices > Print the invoice
This quote relates to purchase orders and direct deliveries. Your original question related to a sales invoice. Which is it?
To clarify my earlier response you have two choices, raise a credit note (or return order) and bring it all back and send it back out, or add two lines to the sales order that in essence creates a credit note or invoice depending which way the price changes.
