I'm looking for a way to prevent a task from becoming a summary (by adding tasks, or moving/dropping tasks, as children) if certain conditions exist on that task. For instance, if a task has had time reported against it, it cannot become a summary.
Can I prevent all the CRUD operations on the Gantt based on checking for a condition on the task that would become a summary? Can I return the data to check as part of the Gantt query? Or would this have to be outside the control?
Thanks for any help or hints
