OK if we look at the Option it referes to both Resources and Tasks. We can see that if you try to add Resources with this Option unchecked you will get an error message i.e. Project is working as advertised.
However, with the option unchecked” and either Inserting a Task to a Gantt chart view or adding a Task to the bottom of a task list within the Gantt chart view no corresponding error message is generated by Project.
I guess what I’m trying to do is Lock the schedule down to indiscriminate TAsks being added without an error message being generated.
