Flow call

Scroll Prev Top Next More

A flow call can be used to call another flow inside a flow.

 

To use the call flow activity, the activity can be dragged into a flow.

Another option is to drag a flow from the Project Explorer, this will create a call flow activity with the dragged flow selected.

Begin

 CoreActivities.Parameters('', DatesList, Shippers);

end;

 

The parameters defined in the flow that is being called are listed in the call flow properties.

The value of the parameters need to be defined to prevent errors. The value can be static values or variables.

The class instance to use is optional for providing a class instance, this is mandatory if the flow is from another flowclass

 

If the flow has a return variable, a return value field appears, where the name of the result variable an be defined.

Tip, always keep an eye on which flow calls which flow. It is possible to create a loop, that will result in a stack overflow...
