An End User cannot edit an Incident Report after they have made a submission. However, as an Administrator, you can make necessary changes to any Reported Incident, including information entered by an End User.
Go to Incident>Reported Incidents and refer to the 'Actions' column beside the Incident to which changes are due to be made; Click View.
You can edit any information in this section, and please also refer to the article 'How to Filter, Customise and Export Reported/Existing Incidents' for further instruction.
