The Invoke Process action is an extension escalation provided by Informatica. This action is based on Informatica-provided WSDL, "Custom B4P Notification", as described in Creating Custom Escalation Actions.
You can deploy a BPEL process to your server and then specify the service name as an escalation action. You might want to invoke a process to send an email to a user, rather than send a notification to a task client application.
To Create an Invoke Process Action:
Ensure that you have deployed your BPEL process that serves as a custom escalation action. This process must be based on the special template, Custom B4P Notification.
In the Properties view, add the Service name of a BPEL file deployed to the same server where your current process will run. You can copy the service name from the Process Console's Service Definitions page.
You must use the special BPEL template, Custom B4P Notification, designed for a custom notification, as described in Creating Custom Escalation Actions.
If desired, create a Data expression for task or other data you wish to pass to the called service. For example, create an expression to determine the task priority or list of potential owners.
