You may want to reorder your work when building your plan, to make the planning process simpler.
You can reorder packages on the Gantt by dragging and dropping them.
Reordering packages on Team Spaces apply this order for everyone on the project, however this can be done on personal spaces without impacting other users.
Tasks have a default sorting order and can not be reordered. The default sort order that tasks appear on the Gantt is:
First by Start Date
Then by Duration
Aphex locks tasks in place whilst you are making changes, if task aren’t ordered in this order, click Tidy Up to reapply the default sort order.
