How to change default value for parameter?

Hi All,

I have a report in Crystal showing weekly figures. The report has dynamic parameter to select a week to run the report. I want to schedule the report in Business Objects XI to re-run the report every Monday morning. The problem is that I want BOXI to change the parameter week automatically every monday morning. Means, if I scheduled the report for week 1, on next monday, it should automatically run for week 2 and week3 on following monday. Currently it stores the week number 1 in the scheduler and runs for week1 every monday.

Any help please?

Thanks,

Zahid
