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.

   | Scope | Steps |
   | All Projects | Navigate to AllProject AdministrationProject Diagnostics. |
   | Single Project | 1. Navigate to AllProjectProjectsAll. 2. Select the project. 3. On the Project form, select the Project Diagnostics related link. {#project-diagnostics__ol_lrs_d45_xjb} |

2. On the Application Diagnostics Tool page, select a diagnostic feature.
3. Use the Feature Inputs fields to specify filter conditions.
4. From the Diagnostics section, run a single diagnostic scan or multiple scans on the projects matching the filter criteria.

   | Task | Steps |
   | Run multiple diagnostic scans | 1. Select the diagnostic scans that you want to run on the filtered projects. 2. Select Run Diagnostics at the top-right corner of the page. {#project-diagnostics__ol_nkb_gp5_xjb} |
   | Run a specific diagnostic scan | 1. Select the single diagnostic scan that you want to run on the filtered projects. 2. Select Run Diagnosis. {#project-diagnostics__ol_l2p_lp5_xjb} |

5. View the results of the scans.

## What to do next

Add your own [diagnostic scans](https://www.servicenow.com/docs/u0WaLzmz8N1LcZ6B2aRc4w "Once you have created diagnostic features and scripts, map them to a diagnostic scan to check the health of data in your application. Use fix scripts to rectify any corrupt or invalid data that the diagnostic scan identifies.") and [fix scripts](https://www.servicenow.com/docs/95cHIKOGBhMglUb_7KR9lA "Add diagnostic scripts to scan the data in your application for any corruption. You can also attach fix scripts to rectify the corrupt or invalid data identified by the diagnostic script.").
