Why might an active project not show up on the Project Details report?

An active project might not show up on the Project Details report due to a lack of activity on the project. Xero typically filters reports based on certain criteria, and if a project has no recorded activity, it may not meet the conditions necessary for it to be included in the report.

This focus on activity means that for a project to be featured in the report, it usually needs to have some logged time or transactions associated with it. If no activity has been logged, Xero considers the project inactive in terms of reporting, even though it remains an active project in the system.

In terms of understanding the context of the other options, an incomplete project would still be listed in the report if it has activity logged against it. Projects that are archived are no longer considered active and wouldn't show up in the report. Similarly, if a user lacks sufficient permissions, they wouldn't be able to view certain projects or details but the projects themselves would still exist in the system and be accessible to others with the appropriate permissions.
