Hi @Jessica_Dumas, @David_Hartstein, it’s not currently possible to switch this off, but I’d recommend creating a Feedback topic in our Product Feedback section so everyone interested can add their vote. You can also share feedback directly with the Product team via the in-product feedback button within the “create custom field” popup.
@Bob_Le_Schoenthal, our Help Center team is still working on the guide article. Sorry about that. In the meantime, you can find more details in this comment from Emily.
Can you confirm if you are referring to the portfolio workload or the universal workload? Portfolio workload only takes into account tasks that belong to the projects that live in that portfolio. The universal workload allows you to view the global capacity of a team by pulling data from tasks and subtasks across all projects into a workload view. However, users looking at the workload view must have permission to see the task. Otherwise the task will not show up on the workload view.
To clarify, this specific feature update means that data created via these rollup formula custom fields can be used in project-level automations, universal and portfolio workload, reporting features, and as inputs to other formulas, but it should not change permissions behavior. I hope this helps clear things up!
