Have you found a solution? Incorrect item cost of sales recorded when creating a sales credit I have a customer who wants to return an item and we also need to return this item to our supplier. Our current stock is zero. When I created a sales credit, I can see from Item register that MYOB records an incorrect item cost. Let's say the item purchase cost is $10 ex GST but MYOB recorded the item cost as $11 now. How do we solve this?
