Please follow the steps below to check your payroll cut-off cycle:
In the Payroll module, click Setup, Pay Group Setup.
Select the Pay Group ID. eg: 1 Payment Group.
Click the 3-dotted button beside the Sub Period Cut Off Date.
Change the start day and end day.
Change the start month and end month.
Click Save.
Note: If you're changing the cut off date in the middle of the month to the 1st of the month, the system will not auto-generate the back pay; you'll need to do it manually for the back pay.
