  • The segment includes nonreusable Sequence Generator transformations, Input transformations, Output transformations, or transformations containing set operations.
  • The selected segment does not include all transformations in a pipeline branch.
  • The first and last transformations in a segment contain dynamic fields.
  • The segment includes incoming run-time links to the first transformation or outgoing run-time links from the last transformation.
