This is more of a general question about Scheduling Requests on the concurrent manager

 I have a request that needs to be run with the following parameters each week:

From Date: Always the first of the current month (1st date of the current sysdate)

To Date: Always the day the request is being kicked off on - so the sysdate.

I schedule this request to run every Wednesday.  It seems as though when the request is kicked off, on schedule, for the following week as soon as the current week is finished running so my 'To Date' is never correct.  When I hit the new month then my From Date is from the previous month.  Is there a better way to use the schedule for concurrent requests?  Am I not using this functionality correctly?
