Error when using 'RunDataFlow' shape in Pega 7.3.1
I am using 'RunDataFlow' shape inside a flow in my application. The source of the data flow is a data set and output is abstract. When I am trying to configure the data flow it gives me error like 'data flow does not support process or save operations'. Can anyone suggest what went wrong here?
P.S - The classes of the data flow and the main flow are different. I am accessing the data flow by defining it on another page.
