You can use automatic instantiation to create a child case when a parent case is created. By allowing your application to monitor case status and events, you simplify case creation for case workers.
Open a child case type in Case Designer.
Caution: Ensure that you open the correct version of your case type if it has multiple parent case types. The instantiation details for a child case type are unique to each parent case type.
On the Settings tab, click Instantiation.
Select the Automatically by system when check box.
Click Parent case starts.
Optional: In the Allow only when field, press the Down Arrow key and select the name of a when condition to control when a child case is created.
Alternatively, you can enter a unique name and click the Open icon to create a new when condition.
Click Save.
At run time, an instance of your child case type is created when your application detects that a parent case is created and the provided when condition returns a true value.
Tip: Open the Case Type form of the parent case type to access more options, such as the maximum number of child cases that can be instantiated in the system.
