Date Format changes in the Reporting side..

Hi friends,

I have one date field that is Keyfigure (not a Time charecterstic) ...now i want to display date in DD- MON - YYYY format... but up to modelling side my date format is DD.MM.YYYY.....

i dont want to change in modelling side.. because.. this required format is needed only for some querys ...

so, can any one suggest me is there any chance to get the date format in the reporting side like this..(27-JAN-2007) ..

helpful answers will be appriciated..

Thanks

Babu
