Pivot Report Formula - using a today() variable

Pivot Report Formula - using a today() variable

Is it possible for me to use a value of today() in a formula on a pivot table?

I'm trying to identify where the end date of a project is greater than the current date
  1. if("10. Projects (Zoho Projects).End Date" > today(), 'Yes', 'No')


I get the error that the specified formula is invalid. The End Date field is formatted as a date.
