# Process Flow Diagram Icons

Below is a table outlining the icons that can appear in a process flow diagram and what they represent.

Icon | Description
| This icon indicates the start of a process flow.
| This icon indicates the default path from one stream to the next.
| This is the stream icon. The stream name will appear in the center of the icon. There are three places on a stream in which the path can flow. The path flows in from the left side of a stream and either out the bottom of the stream, indicating that there is a branch that occurs somewhere in the stream or out the right hand side of the stream indicating that it is moving on to the next item in the flow.
| Paths that are not part of the default flow are indicated by a blue arrow.
| This icon indicates that there is an error in the flow such as an invalid branching condition.
| Paths containing errors such as invalid branches are drawn in red.
| This icon indicates that the flow branches to a stream that is not part of the current process flow.
| This icon indicates the end of a process flow.

Within a process flow diagram, the user can drag and drop the various icons shown above. Moving an icon will not cause it the connectors to detach.

If an object that connects two other objects is deleted from the diagram, the path will reconnect itself, linking the objects on either side of the deleted object together.
