date instead of quarters

Hello Dears,

I would like to display the date as the last day of each quarter instead of the quarter number.

this is what I have, when I receive the Date from the DB I get it in the following format,

Q1 2013               Q4 2012               Q3 2012               Q2 2012

instead I would like to have the last date of each quarter to be displayed as follows,

2013/03/31          2012/12/31          2012/09/30              2012/06/30         

I would like to do this change in Webi not in the Bex query or BW.

Regards,

Mo
