By Pass Cache if the date in the prompt is Current Day

Question

Hi,
We have implemeted Cache solution for few dashboards as performance improvement.
We have a report with date prompt. By default we show previous day data. User can generate report for any date by giving the date in the date prompt.
To improve performance, we get the previous day data into the BI cache. We got lot of improvement with this for default dashboards(previous date is default).
If user changes the date to current date and tries to generate, it gets the data from EBS and stores in the BI cache for the first time. If any user tries to generate after this, then it will get the current day data from Cache not from EBS. This is incorrect. We need to bypass cache if the date prompt is having current day.
We tried the following.
1) We have enabled cache in RPD at the physical layer.
2) This will cache the results in to BI even for current day. We tried to purge the current day query using "SAPurgeCacheByQuery" but after executing it says purged successfully, but in BI RPD, if we check the cache, the query still exists and if we generate report for current day, it gets the data from cache not from EBS.
Any ideas would be helpful in this area.

Answer 1

Hello,
Use an alias on the table where you have enabled cache in repository, and enable the "Override the source table caching properties" make this not cacheable so that you are disabling cache for this new alias table.
Once you have done this also make sure you disable cache at the Presentation for on that single report by going to Answers, go to Advanced Reporting tab when building report, set Prefix value to following:SET VARIABLE DISABLE_CACHE_HIT=1, DISABLE_CACHE_SEED=1, LOGLEVEL=7;
Now this will make sure you are not caching your results at OBIEE , the query will directly hit your EBS tables.
Hope this helps. Pls mark if it does!
Thanks,
