How to get the payroll period based on the filed LAUFD and LAUFI in SAP HR ABAP ?

Hi,

I have values for LAUFD (Run on) = 05.01.2021 and LAUFI (Identification) = RM003.

But the payroll period is for the December,2020.

How to get the payroll period based on LAUFD and LAUFI in SAP HR ABAP ?

Is there any table or FM?

Thanks and Regards,

Shabbir
