We need to create reports that are based on fiscal periods instead of months. The fiscal calendar has 13 periods. An example of a fiscal period is Nov 28th 2004 - Jan 1st 2005 (period 13). I need to run a report for the last 14 periods. For example, if current date falls into period 1, then I want to run the report where my applied date is between period 13 of 2003 through period 13 of 2004. Do you have any advice on how to accomplish this. I created a calculation that says if sysdate = applied date then period. This brings me current period. Now how can I filter based on this?
