Partial period factor not getting calculated Properly

HI Experts,

Need help in Payroll.

I have a scenario where emp joins on 6th of a month. WT 1001 has PC10 =2 (i tried even with 1), WT 1001 is maintainted in IT0008 as 3500 GBP. while running payroll the WT is not factored, its showing the entire amount of 3500 in Payslip. While checking the PCR GPPF, I can see the NO factor(neither /801 nor /802 ) is generated. Please advice, also please let me know if more information is needed. Many thanks for all the help which the members of this portal has given to me till date.

Regards

Mohinder.
