Prefix SET VARIABLE PARAM_EFFECTIVE_DATE not working for Recruiting - Recruiting Realtime

Summary:

For my OTBI analysis, I applied the prefix mentioned in the documentation for the Recruiting - Recruiting Real Time subject area under the Time Reporting heading, but it does not appear to be working to change the default as of date.

Content (please ensure you mask any confidential information):

When I run the analysis for an as of date in the past, before the creation date of a requisition, the requisition still shows up. I was expecting that it would not show up until on or after the creation date. What am I doing wrong? Or does this subject area not allow the as of date reset?
