Hi Sankarsan,
Yes your understanding is correct. An employee, joined before 01.04.2012 can only accumulate maximum 300 Quota and Joined after 01.04.2012 can accumulate maximum 60 Quota. To restrict Maximum Quota accumulation we put the maximum number of Quotas in Max. Entitlement in generation rule.

Clik here to view.
I think it can be restrict Maximum Quota accumulation.
And please tell me the prerequisites before write PCR as you shows.
Thanks
