# Use Project Diagnostics to detect corrupt project data

Project Diagnostics uses the Application Diagnostics Tool to detect corrupt project data. Examples include tasks with invalid parents, tasks without top tasks, and invalid or cyclic relations.

## Before you begin

Role required: it\_pps\_admin

## About this task

Project Diagnostics can also detect whether date calculations in a project appear to be incorrect. It can also identify when the planning console does not open for a project or when tasks or relationships don't appear in the planning console.

## Procedure

1.  Determine whether you want to run a diagnostic scan on a single project or multiple projects.
