To edit an assignment on the Gantt page, click on the project assignment bar beside the person whose assignment you wish to change.

When it comes to editing assignments on the Gantt page, you will have two options:

1. Editing an Occurrence 
2. Editing the Total Assignment

Editing an Occurrence

The 'Occurrence' refers to a specific duration of one assignment without any breaks. If someone is off on the weekends, the past five days they worked would be the occurrence. When editing an occurrence, the changes are only being made to that specific chunk of the assignment rather than the complete assignment range.

Editing the Total Assignment

When you need to make a change that will reflect over the entire assignment range, click on Edit Total Assignment from the pop-up box. Once you have entered the details of the assignment changes, hit Save or Save and Alert (if you wish to notify the person of their assignment changes).
