The Union Processor combines two datasets. The second input is appended to the first input.
The processor has two input ports for the tables to be combined. The two input tables need to contain the same columns (name and representation type). However, the second (right input) table can contain additional columns, but they will be ignored.
Additional configuration is not required.
