Assuming you have appropriate permissions you can complete open incidents (state Open → Complete) by executing the operation Complete:
The Complete operation takes several parameters:
Complete type: select the appropriate state transition type (see below for an explanation of the meaning of the various types)
Title: give your complete action a title that summarizes/identifies your action
Text: provide additional information in this field at a level of detail that is appropriate for the action; make use of the HTML feature to add explicit structure as this makes your note easy to skim (you can start the HTML editor by clicking on the small icon [HTML] located just above the input field)
You can optionally provide information to create an Activity Links (see section Grouping and Linking Activities for information on linking activities):
Activity link: activity to link to / to be linked from
Activity link type: choose an appropriate link type
Activity link name: provide a name for the Activity Link to be created
Activity link description: provide a short description for the Activity Link to be created
You can choose from the following state transition types:
duplicate
to indicate that this incident is a duplicate of an already reported/existing incident (if possible, you should create an Activity Links pointing to the respective incident)
fixed
choose this state transition type if you resolved the incident (e.g. fixed the bug)
invalid
to indicate that this incident is invalid (you should probably provide details in the field Text supporting your reasoning)
later
to indicate that the incident will not be fixed now, but at a later date (the Reporting Contact can Reopen the incident at an appropriate date/time)
moved
choose this transition type to indicate that the incident was "moved" to another Activity Tracker
remind
choose this state transition type to indicate to the Reporting Contact that you would like to be reminded of this incident at a later point in time (provide guidance to the Reporting Contact in the field Text)
won't fix
choose this state transition type to indicate that the incident will not be fixed (you should probably provide details in the field Text supporting your reasoning)
works for me
choose this state transition type to indicate to the Reporting Contact that - in your opinion - there is no issue (you should probably provide details in the field Text supporting your reasoning)
Submit your complete action by clicking the button [OK] (click the button [Cancel] to dismiss your entries). On successful execution of the Complete operation, the incident is assigned to the Reporting Contact.
The result of the operation Complete of the type fixed is show in the figure below (note that the field Assigned to was updated and the State was changed to Open):
The following figure shows the updated grid Notes containing the entry representing the note created by the operation Complete (fixed):
