Thanks Sumeet!! once again you solved my problem 
After I enhanced ICCMP_BT_IRHIST/InrLastHist to redefine OP_DEFAULT- there is no more Navigation error but it discovered one more issue -
It gives me dump in method - GET_LAST_INTERACTIONS in line lr_core->modify( ) asDereferencing of the NULL reference in method DO_INIT_CONTEXT( ). ,
Right now I commented code lr_core->modify( ) and its working fine but I am not sure if it will not create any further problem without this statement.
Please throw some light on this. I hope I am not bothering you more
Thanks,
Priya
