Anand,

CCS forum is a good place to search for CCS-specific answers. For example, regarding your question, see this thread https://ccsinfo.com/forum/viewtopic.php?t=36218.

Also, do read-up on PIC18's interrupt architecture. You might find that it's not very sophisticated. As far as I remember, it has 2 levels of priority: high and normal. But during normal run-time only one (1) level of priority is useful, because high priority is good only for the low-power interrupt (for example you can use the ISR shut down the instrument gracefully and to to save crucial data to non-volatile memory).

Regards,
