Automatically select most recent date from prompt with java script

[sunny bachan prasad]

Hi Cognos Guru,
I am working on dimensional package.I have a small challange where i got stuck and try my best but not able to solve it.
We have to provide the date prompt to user in such a way that it should automatically select the most recent value for the available date in the prompt.
initally we are able to do this with the help of java script but now they dont want java script.

Thanks in advance.
