Modify a rate card cost Configuration item costs often change over time as facilities or vendor rates change. About this task Expense lines are the snapshot of a given interval's costs, so changing the cost does not affect already generated expense lines. When costs change, either modify the cost amount or disable the current cost and create a new cost to represent the cost going forward. The changes are processed in the next generated expense line. To keep historical records of costs, create new costs rather than modifying existing ones and set the end date of the disabled cost to show that the cost agreement expired. Procedure Navigate to Cost > Costs > CI Rate Cards. Select a rate card. Click a rate card cost Number. Modify the fields, as necessary.
