I cannot find any documentation on the usage of the "Group" column for the Output column definitiions. Can someone please explain the usage.

Can you be more explicit? Which "group" property are you referring to and where (Stage/Tab/release/Server vs EE)....

Sorry for lack of detail!!

This field is an attribute of all columns on the XMLInput stage "Output" tab. It is located between the column_name and derivation attributes.

This is being used in a parallel job.

I don't believe that the Group field is used in the XML input stage. The Columns grid is a generic control; the Group field is used when the grid appears in a stage performing an SQL SELECT operation (to add a GROUP BY clause in the statement; non-grouped fields require set operations such as COUNT, SUM, AVG) or in the output link of an Aggregator stage.
