January 2, 2019, update for Project 2016 (KB4461587)

Applies to: Project Standard 2016Project Professional 2016

This article describes update 4461587 for Microsoft Project 2016 that was released on January 2, 2019.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home (see Determining your Office version).

Improvements and fixes

This update contains the following improvements and fixes:

  • After you edit and save a project, the values for some Enterprise Resource Custom fields on the project are lost.
  • Consider the following scenario:
    • You assign a resource to a task.
    • In the Task Usage view, you display the Actual Work and Actual Overtime Work fields.
    • On the assignment, you type 2.33h in the Actual Work field and type 3.33h in the Actual Overtime Work field.

When you compare the actual work on the task with the actual work on the assignment, the values are inconsistent. For example, the task shows 5.66h and the resource assignment shows 5.67h.

  • In some situations where your project is saved to Project Server and where user updates are protected, you may not be able to indent or outdent a task. Instead, you receive the following error message:

Change would modify work entered by a team member.  We can’t make that change because Project Web App is set to only allow actual work to be entered by team members through Timesheets or My Work.

  • When you edit resource properties on local resources while editing from a master project, changes are not saved successfully.
  • You can't create recurring daily exceptions whose periods are more than 1 day and the intervals overlap. As an example, you create a recurring exception that begins on the first day of the month, is scheduled every 28 days and ends after three months. If you try to create another recurring exception that begins the second day of the month, is scheduled every 28 days and ends after three months, the action is blocked.
  • In the Czech language, a corrected translation for Committed Work is made.
