Yes, the End of Period Screen will display all the transactions that are unpproved if you have clicked on the Radio Button that says Unapproved. 

However, it is the period and year listed in the  FOR Period and Year  fields that actually  determines what transactions will actually get approved and posted when you click on the Approve and Post Button. You may print out a list if you would like first of what will be approved and posted by simply clicking on the Print Unapproved Transactions Button. You may also drill down to the individual transactions  by double clicking on the total line for the period in question, and it will display transactions listed.
