Wrong display of No. of days worked in Payslip for mid-month joining

Question

Dear Experts,
We use PE51, form editor for payslip for indian payrol. Our issue is when an employee joins mid of the month or say 4th of any month, still in payslip it shows no. of working days as 30/31 days instead of actual days worked. But pay results are correctly being calculated on factoring basis.
Please let me know how to resolve it, we use PCR ZNP1 for factoring which is written as follows
ZNP1 Partial factors for India - /801(CD), /802(WD), /803(WH),/804(Nom)
      /801 Partial period factor 1
        RTE=TKSOLL Set
        RTE-TKAU** Subtraction
        RTE*KGENAU Multiplication
        RTE/TKDIVI Division
        ADDWT *    OT   Output table
      /802 Partial period factor 2
        RTE=TASOLL Set
        RTE-TAAU** Subtraction
        RTE*KGENAU Multiplication
        RTE/TADIVI Division
        ADDWT *    OT   Output table
      /803 Partial period factor 3
        RTE=TSSOLL Set
        RTE-TSAU** Subtraction
        RTE*KGENAU Multiplication
        RTE/TSDIVI Division
        ADDWT *    OT   Output table
      /804 Partial period factor 4
      /805 Partial period factor 5
      /806 Partial period factor 6
      /807 Partial period factor 7
Please guide, if i need to modify it for getting correct working days display in payslip

Answer 1

in that case the Requirement is to display no of working days of employee in a month
Here working days means
Total Calendar Days - Unpaid days - Paid days =  working days ( please check the said one again since i have inculded the paid days and unpaid days if u want u can remove paid days)
so in order to fetch this
we need Calendar days that is TKSOLL
Unpaid days   check the technical wage types /845  Paid days /846  ( you can have custom wage types too)
Copy a wage type from standrad overtime wage type  that will be  1555
The PCR is as follows
NUM=TKSOLL  (calendar Days)
NUM-E  /846      Paid days
NUM-E /845
ADDWT 15555
Use ACTIO function and insert it any where in Sub Schema XT00
