Clarity PPM On Premise Clarity PPM SaaS


What is the impact of disabling 'Calculate Project after each edit' in Microsoft Project (MSP) with Clarity?

Steps to turn off setting: 

  1. In MSP, click File, Options, and then click Schedule
  2. Select Off for Calculate Project after each edit in the Calculation section.
  3. Click OK.


Release : All Supported Releases



Setting this can cause some unexpected behavior. See an excerpt from Configure Manual Calculation below on the impact of disabling this setting.

  • Tasks are not adjusted or updated based on the dependency chain when you open a Clarity PPM project in Microsoft Project. The dependency chain becomes meaningless.
  • Tasks remain stationary on the Gantt chart.
  • You must schedule a project manually and must shift the task dates.
  • The project appears as it was last saved in Clarity PPM, provided you are not using Clarity PPM timesheets.
  • The summary task is not calculated. The rolled up values of the child tasks are not displayed. As a result, the project level % Complete field in Microsoft Project may display an inaccurate value.
