When opening up a specific Project in Planning Console, Planning Console loads into endless loop/time out transaction
If any Project Task of a Project has an EMPTY Planned Duration, it will cause issues when loading the parent Project in Planning Console. Note, there is a difference between a 0 second Planned Duration and an empty Planned Duration.
The easiest way of determining which task in a Project family - if any - has an empty Planned Duration value, is to navigate to pm_project_task.list (or a list of ALL project tasks) and filter by [Top task][is][whatever-the-parent-project-is]. *Adding the 'Planned Duration' column is important
Once that Project Task is located, simply double-click the Planned Duration cell/row and populate it with a valid value.
