December 12, 2017, update for Project Server 2013 (KB4011598)

Applies to: Microsoft Project Server 2013 Service Pack 1

This article describes update 4011598 for Microsoft Project Server 2013 that was released on December 12, 2017. This update has a prerequisite.

Improvements and fixes

This update fixes the following issues:

  • Actual work that's been reported by team members in a project inadvertently gets spread differently from what was reported. For example, the actual work hours of 2, 2, 2, 2 are changed to 1.78, 1.78, 1.78, 2.45; the totals stay the same but appear differently across the days. This issue occurs in certain situations when the project is edited in Project Web App even though the Only allow task updates via Tasks and Timesheets task setting and display server option is enabled.

  • After an administrative time category name is changed, the new name isn't always used when you create new timesheets. 

  • Time phased planned work values don't display on a timesheet when the Task Settings and Display Reporting Display option is set to "Resources should report their total hours worked for a week".

  • When you delete a value from a custom field that's configured to display a graphical indicator, the record in the database is not deleted, instead the value is set to NULL and the indicator value is preserved in reporting.

  • Consider the following scenario:

    • A project manager publishes a task to a team member.
    • The team member goes to her or his timesheet and enters actual work on the task.

    • The timesheet is submitted and then approved.

    • The project in which the task exists is deleted.

    • The team member goes back to their timesheet.

    In this situation, the task on which the actual work was submitted is no longer there.
