link multiple date fields to time dimension

Hi,

this is probably a simple question. I want to link multiple date columns to
a time dimmension. (order date,order complete date, delivery date,etc). So
far I 've only worked with sales slip tables containing only one date .

is it neccesarry to have the same table as different meassure group in the
cube with the date linked to one of the other fields or is there a better
way?


Regards
