Invoker Step
The Invoker step allows you to choose an Invoker for a process. Invoker components provide the ability to use a service provided by an external system or application. The service is invoked by passing a source message object to the Execute action. The component uses the data provided in the message object to pass the information necessary to use the service to the system or application. An Invoker places any output from the service into the target message object. Typical applications for an invoker component include using a web or SOAP service.
To add an Invoker step:
1. Drag and drop an Invoker step from the Palette to the canvas.
2. Double-click the step on the canvas to open the Step Properties tab.
3. Type a unique name for the step.
4. Create an instance of this component in one of the following ways:
• By clicking the Select Invoker dropdown and then selecting Add a New Invoker.
• From the Configuration tab > Message Components section.
5. Specify the step properties.

Enabled
Select this option to enable the step for execution. If it is not enabled, then the step on the canvas is greyed-out.
This option is useful when troubleshooting a process, especially when there are numerous steps in the process.
Error Handling
Select any of the following:
• Stop Process - (Default) All the steps after the current step are skipped or the entire process is stopped (depending on how you have the error logging options set) if this step stops due to an error.
• Ignore Error - The remaining steps in this process are executed even if this step stops due to an error. This is useful when you want to write a Decision step that can test for the error state of a previous step.
