Transition Conditions And Interlocks

A project definition may have conditions or interlocks configured that control when its transitions may be run.

  • Conditions are rules based on the values of certain folder properties of the project itself or on programming expressions that a System Administrator may have defined.

  • Interlocks are rules based on the values of certain properties of project folders or of documents. Project interlocks apply to the current project or its subprojects; that is, downstream from the project folder. Document interlocks can apply to all, any, or no documents contained with a project folder. Document interlocks can affect the project itself, its parent project, or the topmost project of a project hierarchy; that is, upstream from the project folder.

Transition conditions and interlocks can be simple or very complex. Consult a System Administrator for more information on the transition conditions and interlocks configured in your vault.
