When obligations show in red, it indicates that the Business Date that you are signed in with is earlier than the last date posted on the obligation.

Your Business Date is used as the Posting Date for each stage of the obligation.  You cannot perform any obligation task with a Business Date that is earlier than the latest Posting Date on the obligation.  For example, you Mark for Pay with a Business Date of March 2.  You then unmark the obligation and change your Business Date to February 28 to edit a distribution line for posting to the February General Ledger.  When you edit the obligation, you receive the "The Last Business Date on selected Obligation(s) is later than the Current Business Date" message.  You have to edit this obligation with a Business Date of March 2 or later.
