I have enabled the Event Enabled checkbox on the Roadmap Items object, but I am unable to create a process based on the same. Why?
At the same time, I am able to create processes with the Roadmap object.
The Event Enabled checkbox does not enable objects for processes
The Roadmap Items object is not process enabled.
You can check at DB level:
select * from odf_objects where code like '%roadmap%'
The event enabled flag updates the raise_events column at DB level.
Whether processes can be created for the object is governed by the is_process_enabled column value
In summary, the Roadmap object is process aware, but the Roadmap Items object is not.
