What must be deleted before a project that has tasks, unassigned expenses, and time entries can be deleted?

To delete a project that has tasks, unassigned expenses, and time entries, it's necessary first to remove the tasks and time entries associated with that project. This requirement exists because these elements are integral to the project, and deleting the project without first addressing its related components could lead to inconsistencies in the project's data management.

When a project is active with assigned tasks and recorded time entries, these elements represent work done or planned within the project, making it essential to clear them out to ensure a clean deletion. After ensuring that all tasks and time entries are removed, the project can subsequently be deleted without any remaining dependencies or data conflicts.

Unassigned expenses might not hold any direct linkage to specific tasks or time entries, allowing them to be potentially left in the system should management decide to retain that information for record-keeping or future use. Therefore, they do not hinder the deletion process of the overarching project itself.
