User is unable to add newly created tasks in timesheet.

Summary:
When a project leader creates a new project/tasks they are not available for end users when try to add tasks to the timesheet.

Resolution:
This can be due to the following reasons:

• If Time Entry Allowed is not checked at the task edit page.
• If Assignments page does not contain this users name under allowed list or if ALL is missing (Use ALL only if everyone is allowed access to this task)
