Microsoft Project Prevalidation Messages

Use prevalidation messages to identify errors that prevent export of your project plan from Microsoft Project to Project Management. You must fix all errors before exporting a project.

Identify tasks with prevalidation errors using the indicators in the Exception column in the Gantt Chart view of Microsoft Project.

Tip: After export, review the transfer report to identify if errors or warnings occurred for checks other than those performed during prevalidation.

Prevalidation Checks

The following table describes the prevalidation rules for tasks and resource assignments.

Level	Rule
Milestone tasks	No subtasks are allowed under milestone tasks. Milestones must be lowest-level tasks.
Milestone tasks	Milestone tasks must have zero duration.
Tasks	Only existing labor resources in Project Enterprise Resources will be assigned as labor resources. Including the resource's email address is a best practice.
Tasks	Only existing expense resources in Project Enterprise Resources will be assigned as expense resources.
