How to set up limitation on the number of expenses that a user can record under an expense category?

You can set up limitations on the number of expenses that users can record under the expense category by setting Rules. You can restrict the number of expenses that users can create on a daily, monthly, yearly, or on a custom duration basis. Here’s how:

Click Admin View on the left sidebar.
Go to Settings on the left sidebar.
(OR)
Click Settings in the top right corner of the page.
Select Policies under Users and Control.
Click the policy for which you want to set up rules.
Go to the Rules tab.
Click + Add Rule.
Provide a Name for the rule.
Select a Rule Type.
Set the Limit Type as Expense Count.
Enter the maximum number of expenses a user can create under a category in Expense Count.
Select the Category for which you want to set this rule.
Select the Action Type as Warn or Block.
Click Save.

Once done, any expense that exceeds the number entered in the Expense Count field will get a warning notification or will be blocked from submission based on the action type you’ve selected.
