In Task List, you can choose a task list from the Internal option if you only want to display the task to your portal users. However, if you want to collaborate and display the task with client users, you must associate a task list from the External option.
You can set the default billing type for tasks by adding the Billing Type field in the task layout and fields. The billing type can be None, Billable, or Non-Billable. If you select None, then the default billing status of the project will apply. To set the duration for a task instead of an end date, click Enter Duration and enter the number of days.
If the Start Date of the recurring task occurs on a holiday or a weekend, the previous working day is automatically set as the start date. This option is enabled only if the recurring frequency of the task is set to Monthly or Yearly.
