Hi ,
Same 1st PCR will work in payroll and i have mentioned on my last reply how you can achieve that.
1st use DATES function in Payroll schema after that in the next line use 1st pcr logic (previous link) and thereafter build rest of your logic into pcr. Then i think it will work.
Or else check the below thread. Still you have doubt then i will share the pcr to you.
