How to make Current Month as a default in Dashboard 4.1

Hi,

We've developed our Dashboard on BEx Queries. In most of the screen, users had Calender month in selection screen (e.g. they can select from Jan -Mar ..etc).....Users want current month as a default ..

We can change this manually but how can I set this automatically so every month or week , it should pick correct week (if it's week or month).. Please share knowledge if someone achieve this type of requirement..

Thanks,

PK
