When attempting to save a Microsoft Project (MSP) project back to Clarity, receive error:
Duplicate task ID [Project Manager] found. Cannot continue save.
Note: You may see this error multiple times on the save back to Clarity when clicking OK.
This error is due to duplicate data being stored in Text1 which is mapped to the Task ID field in PPM. The values in this field must be unique in the project.
In 15.7 and lower versions, one reason this can happen is if tasks are copied and pasted using the task highlight feature. This copies over all column data whether visible in the task view or not.
Release: All Supported Releases
To resolve these errors, delete or replace any duplicate data from Text1.
To do this:
1. In MSP from a Task or Gantt view, add the Text1 column to the view
2. Make sure that the WBS task list is expanded in MSP to show all tasks
3. Replace or remove any duplicate data found in Text1
