Union all transformation in SSIS

Union All Transformation in SSIS is used to combine data from multiple sources (excel files, flat file etc) or multiple SQL tables and produce one output to store in the destination table. Union All Transformation in SSIS does not follow any particular order while merging the data and storing in the destination table
It will take multiple inputs. It accepts unsorted inputs.

No need to sort input data.
