Examples include tasks with invalid parents, tasks without top tasks, and invalid or cyclic relations.\n\n## Before you begin\n\nRole required: it\\_pps\\_admin\n\n## About this task\n\nProject 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.\n\n## Procedure\n\n1.  Determine whether you want to run a diagnostic scan on a single project or multiple projects.\n\n<table id=\"choicetable_ez5_jcj_hkb\"><thead><tr><th align=\"left\" id=\"d125854e55\">\n\nScope\n\n</th><th align=\"left\" id=\"d125854e58\">\n\nSteps\n\n</th></tr></thead><tbody><tr><td id=\"d125854e64\">\n\n**All Projects**\n\n</td><td>\n\nNavigate to **All** &gt; **Project Administration** &gt; **Project Diagnostics**.\n\n</td></tr><tr><td id=\"d125854e88\">\n\n**Single Project**\n\n</td><td>\n\n1.

On the Project form, select the **Project Diagnostics** related link.\n\n\n</td></tr></tbody>\n</table>2.  On the Application Diagnostics Tool page, select a diagnostic feature.\n\n3.  Use the Feature Inputs fields to specify filter conditions.\n\n4.  From the **Diagnostics** section, run a single diagnostic scan or multiple scans on the projects matching the filter criteria.\n\n<table id=\"choicetable_hqd_pcj_hkb\"><thead><tr><th align=\"left\" id=\"d125854e154\">\n\nTask\n\n</th><th align=\"left\" id=\"d125854e157\">\n\nSteps\n\n</th></tr></thead><tbody><tr><td id=\"d125854e163\">\n\n**Run multiple diagnostic scans**\n\n</td><td>\n\n1.
