Identifying missed payroll results

Hi Experts,
Can anyone please suggest how to check if employee is missed in payroll run.?
I have FM "PYXX_READ_PAYROLL_RESULT" to get the payroll results. Based on RT table values is there any
possibility to infer employee is missed in payroll or employee is not required to paid?

Please suggest.Points will be given for helpful answers.

Thanks
