RE: Output for sort and dedup sort with null key
I think you need to you need to specify the option whether you need to keep the first or last or unique records as far i know that there won't be any change in records it will exact the same as the original file.This scenario i think you can use to delete any header or tailer records in a file.

RE: Output for sort and dedup sort with null key
If there is no key used in the sort component while using the dedup sort the output depends on the keep parameter.
If its set to firt then the output would have only the first record
if its set to last the output would have the last record
if its set to unique_only then there would be no records in the output file.
