Using View Flow

Use View Flow to see which step the workflow is currently on, who has participated in the workflow, drill down further into the workflow to view the activity data fields. The View Flow can be accessed from the Workflow Instance report as well as from the K2 Worklist menu.
When the View Flow icon is clicked the View Flow page will open with Workflow, Comments, Attachments, and Charts tabs.

The workflow will be displayed in the body of the tab. Various colors and icons depict where in the process the workflow is. You can click on any of the steps or outcome lines to see more information.

To interpret a View Flow diagram, remember:

  • Line Rules that evaluated true and were successful are colored green
  • Line Rules that evaluated false and were not successful are colored red
  • Skipped lines or not yet evaluated lines remain clear
  • Green workflow steps indicate that the step was successful
  • Blue workflow steps indicate that the activity has started, and is in an Active or Running state
  • White workflow steps indicate that the step has not yet been executed
  • Blue events with red exclamation marks indicate that the event is currently in an error state

Process Instances of workflows that have Comments enabled will display the associated comments in this tab.

Process Instances of workflows that have Attachments enabled will display the associated attachments in this tab.

The Charts tab of the View Flow represents the activities in relation to each other graphically. The Pie Chart is opened by default. When hovering over an activity, the activity name is displayed with the running duration.

Click on the Bar Chart icon to open the Bar Chart. To return to the Pie Chart, simply click on the Pie Chart Icon.
