Work Order Completion Dates

Hello experts,

I'm trying to see if there is a T-Code I can use to track how accurate my planners are with finish dates that they put on a work order.  For instance, if the basic finish date is 04/02/2014 and the order was closed on 04/04/2014, then it was not closed to the date that we anticpated.  Is there a report or T-Code I can use to see these dates for my planning team?
