Paid Days coming wrong in Z salary register

Dear Experts,

I have an issue. The issue exactly is that the paid days is coming wrong in Payroll, and thus showing wrong in the Z report for salary register. So now, for calculating paid days, 2 wage types are created:

1PDY - Paid Days

1UPD - Unpaid Days

So now 1PDY is coming wrong as 24, which should be 29, and it should include 4 sundays, 3 holidays (Independence Day, Janmnashtmi, and Rakshabandhan). The system is not calculating these holidays. I am not able to find out where the rule is given, as it does not come in Time Evaluation, as time evaluation is not activated here. It is directly calculating in payroll. Kindly help me to find out the reason for this issue.

Thanks and Regards,

Bhagyashree
