Hi Gail,

Item Inquiry has 2 different menu choices. One includes cost information and the other does not. You can use Group Security to disallow 'View Items with Sales/Costs' and give View access to items for a user but suppress the costs.

You currently cannot allow access to Edit IC Items and disallow viewing the Cost amounts. There is no 'field-specific' security where you can grant access to a function but hide particular information.
