Subset components are the entities, groups, and templates or XSD files in a data subset operation. When you create a plan for a data subset operation, select the subset components that you want to include in the workflow.
When you run a data subset operation on a relational or flat file source, you can restrict the subset operation to specific entities in the project. You can choose the entities, groups, and templates that you want to include.
When you run a data subset operation on an XML data source, you can select the XSD files that you want to include in the operation.
The
Add Subset Components
dialog box shows the entities, groups, templates, or XSD files in the project. Select the components that you want to apply in the data subset operation. The PowerCenter Integration Service performs the data subset operation with the components that you select.
