If you need to edit the more specific details for a Task (other than those parts discussed in the "Quick Editing" solution) and have the required permissions, you must click on the Task name to enter the Task Details Page. Once the Task in question is open, click on the "pencil" icon on the top right (as per below image) - you will be taken back to the Task form to edit any parameters. The same method can be applied to edit Sub-Tasks.
If you change context in Sub-Tasks, WeTrack will automatically add this information into the parent Task to keep data consistent across the system. If you are altering the nature of a Task, you must make sure that you also change the relevant parts of any Sub-Tasks.
NOTE: All changes will be logged in the Task's audit history.
