I have a report which shows calculated data in pivot tables for last four weeks i.e, 30,31, 32, 33 (week number as heading ). I just have week number column in the presentation folder .
I do not want to
* Make any changes in repository or ETL
* Also, I do not want to put CASE statements with 52 statements for 52 weeks as it will affect the performance.
Please let me know if anyone has the solution. I have a week starting from Monday to Sunday. So I would need Sunday's date as week ending dates in my OBIEE 12c report.
Thanks
