We have done a refurbishment job for a Serial tracked product but I cannot see that figure under my Refurbishment Cost box.
When a Refurbishment Job is done, the cost is added to the individual serial number of the product. Not the Latest Landed Cost.
If you cannot see the costs in this screen, as the image below
Check Admin / Defaults / Manage Product Defaults and if the Hide Conts in Product Enquiry flag is selected then the Refurbishment cost will not show for Pre Delivery products.
