The Integrator Concat process object concatenates multiple input flows together; the output column set is the union of all the input columns. If a column is requested in the output flow that does not appear in all the input flows, the value of that output column will be null in the appropriate rows.
Concat Attributes

| inputs (required) |
Array of Strings | Defines the name of the input flows to concatenate, in the order of processing. |
