When saving back a project from Microsoft Project (MSP) to Clarity using the MSP Plugin / Interface, receive error: 'Project Save Failed' due to one or more issues with Start and / or Finish Dates for tasks in MSP.
In the app-ca.logs, you see the following Warning message 'ImportTaskProcessor.doProcess(): Illegal Task Start and/or Finish dates' related to schedulers.postProject.
Tip: To get to the app-ca.logs, see the following KB that will walk both On Premise and SaaS customers on steps to retrieve the log: Access the app-ca.log or other Clarity Logs
There are a couple of causes for this issue, but below is one method to reproduce this issue:
Steps to reproduce:
Expected Results: Project Saves successfully and the project imports successfully to Clarity
Actual Results: Receive error message 'Project Save Failed' and project does not save back to Clarity
This issue happens when there is an invalid date (or invalid date sequence) that is not supported with Clarity including:
2. The Start date of any task is greater than the Finish date of the task. The Start date of a task must be less than or equal to the task's Finish date to be able to be saved back to Clarity.
Component: Clarity Microsoft Project
If any tasks are found with this issue enter the missing dates for the task(s) in MSP (or change the Task Mode to of the task to Auto Scheduled which will automatically populate a Start and Finish date for the task)
Note: To prevent this issue going forward, ensure that the following Required setting is made for the existing project and all new projects in MSP:
Note: Change Scheduling options for this project from the existing project to All New Projects to then make this the default for new projects going forward. Screen shot below:
After initial task creation, the task can then be changed to Manually Scheduled. For more details including steps to change this, see: MSP Manually Scheduled Tasks / Milestones
Update the task dates so that the task's Start date is earlier than the task's Finish date
