Can I restrict the number of attendance regularizations for staff?

Yes, you can set policy P56: Limit Time Correction requests from staff
By enabling this policy you can limit staff to regularize attendance up to X days a month.
For eg: If you set the value of ‘X’ as 3, then staff will be able to regularize attendance up to 3 days a month.

To enable this policy please follow the below steps:

Log in to Admin Web Dashboard > Settings > Policies > Click on “Add New Policy” > Seach for policy P56: Limit Time Correction requests from staff > Click on the “+” Sign > Setup the values according to your requirement > Click on “Add”
