We have an issue with some tasks not being able to be edited to be set to "Completed" or the % complete is set to 100% but the status still says "Started" and cannot be edited to "Completed" while other tasks are not facing this issue.
- The issue with task status and % Complete not being editable can happen if the % Complete Calculation on the Project is set to Effort and there are any non Labor Resources assigned to the task.
- Additionally, the issue with task status changes not saving even if the % Complete calculation of the project is set to Manual can be due to there being ETC left on the task.
For the % Complete Calculation Method of Effort, non labor resources are not included in the calculations. In order for the task % Complete and Statuses to be able to changed, the project % complete calculation method would need to be Duration or Manual. Note: It is not recommended to change a % Complete Calculation Method of a project once it's been set as this can impact the task data.
Note: Even if the % Complete Calculation Method of the project is set to Manual, in order to be able to save a task status of Completed, there must be 0 ETCs on the task. See KB000103580 for an error you can see on the Gantt when trying to update a task with ETCs greater than 0.
Reference % Complete Calculation Method section of the Create Projects, Teams, and Tasks documentation for details on the differences in the three types of % Complete Calculation Methods.
