You can view or change the cost of any item by pressing <Ctrl-Page Up> while that item is highlighted. If your system uses passwords, you can access the cost only if you have a sufficient password level. (For more information on passwords, refer to the chapter Update Passwords in the System Maintenance section of the manual.) If you have used a valid SKU number, the cost should already be correct so you shouldn’t have a need to change it here. If you used a dummy SKU number, you may very well want to change the cost since the dummy SKU number will have a zero-cost.
Changing the cost of a sales item does not change it in the inventory file. The cost entered here is used in the Sales Reports for Select Items and the Sales Analysis Reports.
