In Microsoft Project (MSP), % Complete is incorrectly showing as 99% for one or more tasks, while in Clarity PPM it is showing as 100%. Another symptom reported can be that the % complete is being calculated based on on start/finish dates, but it's expected the % Complete should be able to be set manually. 


This issue can happen if the MSP Option 'Updating Task status updates resource status' is checked. It is required to have this unchecked when integrating MSP with Clarity.


Release: All Supported Releases
Component: Clarity PPM Microsoft Project


Uncheck 'Updating Task status updates resource status'  using the below steps:

  1. Open the project in MSP
  2. Go to File, Options
  3. Select Schedule
  4. Scroll down to the Calculation options for this project section
  5. Ensure the setting under 'Updating Task status updates resource status' in unchecked. If not, uncheck it and click OK.


  • This change will also need to be set for all projects going forward to prevent this issue. To do this:
    1. Under the Calculation options for this project, select 'All New Projects'
    2. Uncheck 'Updating Task status updates resource status'
    3. Click OK.
  • To review all required and recommended settings in MSP in working with Clarity PPM to make sure these are set correctly, see  Configure Default Settings in Microsoft Project to Use With Clarity.
