The [Dependencies Among Jobs](https://community.denodo.com/docs/html/browse/6.0/scheduler/administration/creating_and_scheduling_jobs/configuring_new_jobs/dependencies_among_jobs) is a section available only with the cron time trigger.
For your case, I would set the job’s cron expression to execute in a future date like ‘29 Feb 2020’. Meanwhile, I can still start my job with dependencies manually.
Additionally, if you still need help and if you are a user with valid Support account, you may open a support case at the [Denodo Support Site](https://support.denodo.com/MainPage.do) and the support team will help you.
Hope this helps!
