DD-MMM-YYYY date format in Siebel BI Reports

 Hi Team,

We have once request from the client to change the date format from MM/DD/YYY to DD-MMM-YYYY format.

I have changed the same in Dev envirronment using the below function

<?format-date:psfn:getCanonicalDate(Planned2);'DD-MON-YYYY'?>

but same is not working in Prokduction Environments.. getting the error(Erroro<?>invoking method '<?>' for bussiness service "<?>"

Also another point i wanna raise is we dont have siebel Tools for Production then how can we deploy the Changes Integration object? Is Repository migration the only option ??

When  checked further the sample XML is different in development and production environment.. how can we sync them??
