This activity can be used in both Microflows and Nanoflows.
The Microflow call activity can be used to call a microflow.
Arguments can be passed to the microflow and the result can be stored.
There are two sets of properties for this activity, those in the dialog box on the left, and those in the properties pane on the right:
The Microflow call properties pane consists of the following sections:
3 Action Section
The Action section of the properties pane shows the action associated with this activity.
You can open a dialog box to configure this action by clicking the ellipsis (…) next to the action.
You can also open the dialog box by double-clicking the activity in the microflow or right-clicking the activity and selecting Properties.
The microflow that is called by this activity.
Depending on the selected microflow, you will see a list of its parameters in a table. Parameters pass data to the activity.
The name of the parameter that is read-only.
The type of the parameter that is read-only. For more information on possible types of parameters, see Data Types.
The Edit parameter value button allows you to edit the argument value. For each parameter of the microflow, you need to supply an argument of the same type. The values of the arguments are expressed using expressions. There is a difference in the way argument values are passed to a sub-microflow:
- Lists and objects are passed as references (meaning, if the list/object is changed in a sub-microflow, the original list/object is altered)
- Primitive types (strings, numbers, etc.) are passed as values (meaning, they are immutable, and not changeable via sub-microflows)
When used inside a nanoflow in an offline profile, only primitives and non-persistable entities that have no associations with persistable entities are allowed as arguments for the call. For more information, see the Microflows section of the Offline-First Reference Guide.
3.3 Task Queue
If you want the microflow to run in the background using a task queue, then you need to do the following:
- Check Execute this Microflow in a Task Queue.
- Identify which task queue it should run in in Select Task Queue.
For more information about task queues, see Task Queue.
3.4 Return Type
This read-only property indicates whether you will retrieve a variable, object or list.
3.5 Use Return Value
This property determines if the returned value from the called microflow should be available in the rest of the current microflow or nanoflow. If Use return value is set to Yes, you will need to fill in the name of the variable, object, or list returned by the activity.
3.6 Variable Name, Object Name, or List Name
The name of the variable, list, or object returned by the activity.
