S’applique à : Project Standard 2013Project Professional 2013

This article describes update KB3178713 for Microsoft Project 2013, which was released on April 4, 2017. This update has a prerequisite.

Improvements and fixes

This update includes the following improvements and fixes:
  • Consider the following scenario:
  • In this situation, the given feature pane isn't displayed as expected.
  • In some circumstances, leveling on a week-by-week basis pushes tasks to the end of time (12/31/2149). Meanwhile, the leveling operation takes a long time to complete, and Project 2013 is unresponsive during that time.
  • When you open a project file from a SharePoint site through the Recent menu in Project 2013, the file is opened with read/write access, and you are not prompted to check out the project even though the Require documents to be checked out before they can be edited? SharePoint option is enabled.
  • When you assign a task to a resource with a max units 0, the assignment units is unexpectedly assigned as 100%.
  • Removing the start date from a resource assignment may cause the start date of the task to reschedule to "as soon as possible", and this may cause huge leading splits on the assignment.
  • When you edit an assignment finish date from a Task From type view, Project 2013 may crash.
  • When you open the Build Team dialog box in Project 2013 and enable the Online status next to name display option, Project may crash.
