How to get the Heading for desciption coloumn of the employee

Hi All,

Generally if we display the Employee Value as Key and Text in Bex report.

Employee no:

22222                   Rajesh

33333                   Ramesh

I need heading for Description Column as Employee name, so is it possible to get like this in reporting level? or we need to add new field in cube only and add in report? Can anyone advise me.

Thanks
