How are you entering your purchases? Numbers do not change of their own accord. You need to answer the question "What number are you referring to?" As I mentioned in my first reply, User cost 1 & 2 are manually entered, as is Standard Cost. Receipts entered through Purchase Orders can change these numbers, but you do not have this module.

How are you expecting costs to be calculated if you do not enter receipts? Perhaps a discussion with your Adagio Consultant about how Inventory Costing works might be worthwhile? Or you might read the section in the manual you'll find in \Softrak\Manuals.
