the report doesn't display any data but the query get the data

hello

i have custom report and when i run this report display the data normally after i edit the Query of the report to add some column the report didn't display any data

note : in TOAD the both Query (before & after) editing work normally and fetch the data that i need but when i run the report from generate xml file or run it from the application didn't display any data

other note : the report have several parameters and all of those parameters are optional not required

if the query after editing have a problem it's by logic doesn't get any data in TOAD
