Press cancel button to end the database connection

Hi Team,

when ever user opens the invoice work bench form with out doing any action user is getting "press cancel to end this database operation" ,after pressing cancel button for three to four times user is able to access the work bench forms.

Any suggestion,should we need to work with the profile options 'FND: Enable Cancel Query'.

Please suggest.

Thanks,

Govardhani Ethirajan.
