A developer created three Rollup Summary fields:
Total_timesheets_c, Total_Approved_timesheet_c and
Total_project_Timesheet_c in the custom object, project _c Now, the developer is tasked with created a new field to show the ratio between rejected and approved. what is two benefits using formula field instead of apex trigger
1.No test methods will be executed during deployment.
2.A test class that validates the formula field is needed for deployment.
3.Using a formula field reduces maintenance overhead.
4.A formula field will calculate the value retroactively for existing records
