Creating expense related report with OTBI

Summary

Creating a report which captures expense reports submitted 60 days after expenditure date

Content

Here at Boise State, if someone submits an expense report 60 days after the expenditure date, then the reimbursement is taxable.  Using OTBI, I'm trying to create a report which will show all expense reports that have been paid and that were also submitted 60 days after expenditure date.  Using OTBI, I'm able to use the "expense number" and "submission date" fields, but there is nothing available for the "actual expenditure date". 

Any thoughts?
