Definition Of Operation
It is possible to execute the following batch operations:

After selecting the operation, fields may appear with additional data that is either optional or required to perform the operation. When canceling running process instances, you can optionally select to skip custom listeners and provide a cancellation reason. In addition to the ability to specify the desired operation, a search query can be specified which defines the affected process instances.
You can copy a link to the current search query to your clipboard by clicking on the button and you can save search queries to your local browser storage by clicking on the button and inserting a name in the drop down menu that appears. You can then retrieve the search query by clicking on the button and selecting the chosen name in the drop down menu.
Please note that some operations can only be executed on running instances, while others can only be executed on finished instances. You will see an appropriate notice once the operation type is selected.
Navigation to the next step is disabled as long as all required data to perform the operation is not filled out.
The instance search operates on the history endpoint of the engine. In case the requested historic data is not persisted to the database, then the search does not deliver the desired results.
Confirmation Of Operation
In the next step of the process, you can review the operation that is going to be performed. One can see a short summary of affected instances count as well as a button which toggles display of extended information. In the section with extended information, you see a path to the REST endpoint that will process the request as well as the payload of the request.
On the results screen you will see the current status of the batch operation creation. Upon successful batch creation, the user is able to navigate to batch monitoring. In case of error, this screen will display a corresponding error message.
