Issue/Introduction

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 tasks missing Start or Finish dates

In the app-ca.logs, you see Warning message 'ImportTaskProcessor.doProcess(): Illegal Task Start and/or Finish dates' related to schedulers.postProject.
Tip: To get to the app-ca.logs, see Access the app-ca.log or other Clarity Logs that will walk both On Premise and SaaS customers on steps to retrieve the logs.

Steps to reproduce:

1. Export a project from Clarity to MSP
2. In MSP, go to File->Options and set New Tasks created to Manually Scheduled using the below steps:
   1. Click on Schedule on the left hand side
   2. Set 'New tasks created' to 'Manually Scheduled'
   3. Click OK
3. Create a new task in MSP and leave the Start/Finish Dates blank
4. Attempt to Save the project back from MSP to Clarity

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

Cause

This is working as designed as Start and Finish Dates are required fields for Clarity.

• A blank Start/Finish Dates happen if a task is are created in MSP with Task Mode of Manually Scheduled.
• If the Start / Finish dates haven't been manually entered, the project will not save back to Clarity as Clarity requires Start and Finish Dates for all tasks.
• The value entered must be in a date format, so placeholder values such as TBD or N/A are not allowed as well.

To check if a task is set to Manually Scheduled: view the Task Mode icon for the task. A blue thumb tack indicates it's a manually scheduled task. Screen shot below that shows a task that is manually scheduled with Blank Start and Finish Dates.

Resolution

Check for any tasks missing Start or Finish dates (Date fields are blank or have some other type of value such as TBD or N/A) in the date fields.

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:

1. In MSP, go to File->Options
2. Click on Schedule on the left hand side
3. Set 'New tasks created' to 'Auto Scheduled'
4. Click OK'

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
