While export programmatically, with dot net 4..6.1 getting error as Object reference not set to an instance of an object. But this happens only for huge volume of data, but not for small data. I have used crystal dll version 12. What is wrong with it.

Go here and check the Platforms list to see that 4.6 is no longer supported, 4.7 or 4.8 only

Also what SP are you using, get the latest SP 39 from the link above.

It this a WEB or Desktop app?

FYI - when you see Object reference not set to an instance of an object it means the report is not in scope
