Aggregator Step
The Aggregator step allows you to choose an Aggregator instance to add to a process. The Aggregator component assembles a data object from individual message object. It is done by passing a message object containing a part to the PutMessage action. The Aggregator component must know when all the parts have been provided to produce the complete data object. The input message contains information that indicates the Aggregator on how to become part of a complex object. A typical application for an Aggregator component includes assembling complex documents from discrete parts.
To add an Aggregator step:
1. Drag and drop an 
Aggregator step from the Palette to the canvas.

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 Aggregator dropdown and then selecting Add a New Aggregator.
• From the Configuration tab > Message Components section.
5. Specify the step properties.

Aggregator Step Properties.
Property Name | Description |
|---|---|
Name | Unique name for the step. |
Description | (Optional) Description of the step. |
Enabled | Select this option to enable the step for execution. If it is not enabled, then the step on the canvas is grayed-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 set the error logging options) 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. Note: The Break after first error Logging Option on the Configuration tab overrides the Ignore Error option in the step level, hence when you set the Ignore Error option at step level, you should uncheck (disable) the Break after first error Logging option for the Ignore Error to be effective. |
Select Aggregator | Select an aggregator instance. These instances are displayed when you add an aggregator message component in the Configuration tab. For more information, see Adding Message Components in Configuring Processes. |
Action | Select the action for the aggregator instance. |
Parameters | Parameters for the selected action. Specify the values for the parameters. |
Properties | Properties for the selected action. Specify the values for the properties. |
Note: The Actions, Parameters, and Properties are specific to the component type. For information about this, based on the component instance selected in the Select Aggregator drop-down list, see the component type in Aggregator Step Components.
