Question

Sometimes the "Grouping" icon appears in the Mapper Tool Palette, and sometimes it does not.
Please tell me when it is displayed.

Answer

The "Grouping" icon appears in the Tool Palette only when the data model of the destination component is XML type, not table model type.
　
If you would like to output grouped results to table model type data such as CSV or RDB, you can use Mapper in sequence as shown below, grouping the data in the first Mapper to a XML data and then outputting the XML type data to the table model type component in the second Mapper.
Input data → Mapper:A → Mapper:B → Output data
　
For details on the "Grouping" icon, please refer to the following manual.
