You will need to enter the leave deduction in the following month manually if the no-pay leave (NPL) is applied after your process pay. However, if you would like this to be automated by the system, you need to change your No Pay Leave cut-off period in the system, as it defaults to the first to the last day of the current month.
Please do as follows to change the NPL cut-off:
Go to the Payroll module, then click Setup.
Select Pay Group Setup and click on Leave Cut Off Date three dotted button.
Click on NPL and change, eg, 16 Previous month to 15 of the Current month or 20 Previous 19 Current and click Save.
