Hi Tandrima.
I have a correction to add to my earlier post...I said do your PCR before additional payments and deductions...but it should be after...assuming the slab amount comes from IT0015. I don't know how you are getting your slab amount to determine the actual deduction.
I created a simple scenario in my system...I loaded a payment on IT0014...and then starting the second pp...I use the YTD value from previous and overwrite the deduction amount from IT0014. I was able to do this by checking if YTD value exists...if its 0 then IT0014 deduction will happen...if its a non-zero...then I used a constant table entry as slab...so deduction is constant table entry - YTD value...this worked fine for me.
below is my PCR
