Comparing a MaxDate with another Date field

Hi there,

I am trying to create a report that has  components on it, ReportDate, MaxReportDate, and JobID. I want to compare a max date with another date in my Web Intelligence report. For example, I have a field called Report Date. I have applied the Max() function to find the most recent date in the list of Report Dates. Therefore, I used this:

Max([ReportDate]) --> MaxReportDate

Then I want to compare the original Report Date field with the MaxReportDate and return the JobID if the ReportDate = MaxReportDate. Therefore, I used this for the JobID2 formula:

= [JobID] where (ReportDate = MaxReportDate)

This is not working. Am I doing somehting wrong? By the way, I am using SAP Business Objects BI Platform 4.0 Client Tools (version 14.0.2.364).

Please help! Thanks!
