Auto Pull for Expense Reports

Auto Pull for Expense Reports

Hello, 

I have added the automation for our main approver to get the expenses pushed to here through the automation process. 

What I wanted to know is how that actually works. I have checked the box for there to be a report generated even if there are no expenses, but she is only getting email notifications that there are pending expenses. None of my expenses are getting pushed automatically for her to approve. 

Do I need to make them into a report for her to be able to get them or does the automation process push expenses into a report by itself and then send them to the approver?
