Validity of the filters in open reports

Question

I have a report in which I implemented a filter, in order to show only records where the "expiration_Date" (which is a datetime column in the data object) is before than the current system date (using the "now()" function).
So far so good, the filter works perfectly. But if I keep the report opened in Active Viewer, and meanwhile the current system date becomes greater than the expiration date, the report doesnt' get updated, I have to manually click the "refresh" button in order to reflect the change. But in my opinion the report should have refreshed itself.
Does Oracle BAM periodically check for the validity of the filters in a open report, like it does with updates on data objects?

Answer 1

No, all filters are static except 3 with these comparison conditions "is with in a time interval", "is with in a time period", "is with in the current time period" used with "Active Now" option. These filter conditions provide sliding time window based updating itself automatically and periodically based on the interval given in Active Now Interval text box.
So, for your case, using "is with in a time interval" condition should work like this:
"expiration_date" "is with in a time interval" "previous" "4" weeks. Check Active Now box and you could leave the default of 60 seconds for Active Now Interval.
You can change "4" and "weeks" to reflect the range of your data. So, what this condition will do is show you all records in the last 4 weeks whose expiration_date is less than "now"; every 60 seconds, "now" will get updated automatically to the current time, there by making your previous 4 weeks to start from then on, thus removing those older records which don't satisfy this condition.
Hope this helps.
