The source of a summary column may be any column within or below the summary column's group (with a valid Datatype for the function).
If you change the Source of a summary column, the Datatype of the summary column changes to reflect the Datatype of the new source column, unless the column has Read from File specified.
Any column can be the Source of multiple summary columns.
If you specify a source for a summary column and later delete the source column from your report, your summary column no longer has access to data to summarize.
