Process flow keeps its data in a memory called Process Flow Context that is used by the process flow during its execution. When a process flow takes any data from the context, it uses the context source activity. Context Source is used to read a variable and stream it out to other activities of the process flow. In addition, Context Source can also read a file from the repository (WebDAV or File) and pass it to other activities. Similarly, when a process flow sends any data to the context, it uses the context target activity.

To create a Context Source/Target activity:

  1. In the Process Designer, in the Repository View panel, expand Activities > Source > Context Source.



  2. Drag the Context Source to the Graph Canvas area.



  3. In the Graph Canvas area, right-click the Context Source and click View Properties. Alternately, you can click the Context Source element. This displays the properties of the context source at the Bottom Pane.


    A list of properties and their descriptions are displayed in the table below: 

    Properties
