Hi Omid,
Thank you for you reply, actually, payroll and time period are both from 1st to end of month,
but user runs payroll not on a fixed date, maybe on 27th or 28th, time data from that day to 31th is not ready,there will be different payroll result between 27th and 28th payroll run,
so they want to use time data from previous 28th to current 27th regardness of payroll run date.
