Basically, all mandatory settings need to be filled in. Missing settings are highlighted in the Details panel, and warnings inform you what's missing.

In general, it depends on the calendar event type:

Calendar Event Type	Prerequisites
General task	Needs at least one assignee.
Review task	Needs at least one assignee. Note In composite tasks, that include the review step, people who review the work result are called reviewers. In review tasks, the reviewers are assignees of the review task.
Composite task	Needs at least one assignee. Needs different users as assignees and reviewers. You can't add the same person as assignee and reviewer.
Data locking task	Manual data locking tasks need at least one assignee and a context defined.
Process	Needs either at least one assignee, or valid child events

Only calendar events that meet the necessary prerequisites are considered to be valid, thus they can be activated.

If you've selected Dependency as start condition of your event, you can only activate it when there's at least one valid dependency event. If all of them have been removed, for example, you need to add other events as dependency events before you can activate your event.

If you've selected Parent Process as start condition of your event, you can only activate it when the parent process is valid.

When you activate a parent process, only child events that are valid can be activated and can receive the transferred roles of the process.

Your process seems to be invalid to serve as parent process for your event.
