| # Schedule Segments (tdipu0115m000) Use this session to list and maintain purchase schedule segments. A segment can be specified by adding a segment time unit, a segment length, and a requirement type. If you use non-referenced schedules, segment sets are used to: Regenerate schedule lines, which you can perform in the Regenerate Schedules (tdpur3211m000) session. Cluster schedule lines to generate release lines with the status Preview, which you can perform in the Generate Release Lines (tdpur3222m000) session. If you use referenced schedules, no segment sets are used because these schedules are immediately put into a purchase release with the status Scheduled. Consequently, the requirement type is always Firm.
