Continual cycle: Each continual cycle has a dedicated task list. Once the cycle is closed, the task list is closed as well. If there are open change documents or transport requests for the cycle, the system displays an error message and the cycle cannot be completed. The change documents and transport requests must be finished before the cycle is completed.

Phase cycle: Each phase cycle has a dedicated task list. The task list is closed once the cycle has been closed, all change documents have been completed, and the transport requests have been imported into the production system. If there are any open change documents or transport requests, they are assigned to the next phase cycle and the task list is continued.

When a phase cycle is completed, you can create a new successor cycle if all change documents have been completed and all transport requests have been imported into the production system. In this case, the task list is also continued, that is, the old cycle is completed and the new cycle continues with the old task list.

Release cycle: For all release cycles that have the same change control landscape and branch, the same task list is used. When you put a release cycle in the “Hypercare” phase, the following release cycle takes over all unfinished change documents and continues the task list.
