Solution

  • You can create a cmd task which will kick off on a condition.

    1. in cmd task just put this command
    touch /location/empty_file.txt
    1. Link main session to this command task. Double click on link and add below condition to link.
    $yourMainSessionName.SrcSuccessRows = 0

    So, this command task will activate only when your main session pulls 0 rows.
