To enable Tasks numbering, select Settings > Helpdesk settings. When you mark 'Tasks numbering' checkbox, you will see the following window:
where field:
- Example patterns - allows you to select numbering pattern and period after which tasks will 'restart'
- Initial number - initial value for your tasks numbering
- Pattern scope - if you want to enable tasks numbering only, select 'Separate patterns for tasks and emails'. You can also merge numbering, then new emails and tasks will share numbering
Note: if you delete a task or an email, its number will be remembered by the system, so you won't be able to give the same number to a new post.
