Hi,
I think in your time evaluation run public holiday wage type it's coming to payroll ZL table (might be any PCR has been written) and which will be added to in result.
Please share following table details after time evaluation run from Payroll log.
1. ZL table output
2. PARTT & PARTA Table output
3. INP1 PCR (might be customized one will be present)
4. INP1 output result.
5. XVAL pcr output result(could be customized one present).
6. RT table output.
Kindly cross check.
Regards,
