defining operator in Analysis for office.

Hi Experts,

I have a requirement to put <= operator on calender day field in analysis for office. I'm so use to webi that didn't realize there's no option/feature in analysis that can directly let me select an operator to achieve the results. I'm working on a report that needs all the transactions processed before a certain date.

Is there any way i can use a operator to get the desired results.

Let me know if more information is required on this .

Thanks
