Error when trying to use this query in report region

Question

Hi ,
I am getting "1 error has occurred
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-00933: SQL command not properly ended"
while trying to use this query in reports region .
Pls help.
Thanks ,
Madhuri

Hi, I am actually stuck here. Can you please let me know which among these is the higher version.
1) Final Release 3.50
   Version 3500.3.016
2) Final Release 3.50
    Version (Revision 481)
Because it is working fine in the 1st one whereas its throwing that error pop-up in 2nd one(as soon as we select the Change query global definition option) .
