Hello Harshit,
I do not want to seem rude, but PB 8.0 is dead and buried.
Without knowing your environment, how can we be of any help?
200000 rows are nothing on current commodity hardware and modern operating systems.
I suspect you hit memory limits running legacy code generated by 20-year-old PB 8.0 compiler.
Have you tried upgrade to PB 2017? The upgrade steps are easy, and you would have tons of benefits.
Best,
Marco
