What action must be taken to create an Expense Limit in the Expense Limit/Rate Tab?

To create an Expense Limit in the Expense Limit/Rate Tab, it is necessary to deselect the Rate checkbox. This action indicates that the system should treat the entry as an expense limit rather than a rate limit. By doing so, the configuration clearly defines that the focus is on setting a cap on the amount that can be expensed, which is essential for effective budget management.

Selecting the Rate checkbox would imply that you are instead configuring a rate, which is relevant for different purposes, such as hourly billing or per-unit pricing, rather than establishing a ceiling on expenses. Modifying the Rate Unit field and setting cascading options are both related to how rates are processed and applied but do not directly pertain to the creation of an expense limit itself. Thus, the correct choice highlights the important distinction between these functionalities within the system.
