How can I uninstall the PSA solution?
I get stuck with below dependencies: Contract Status and Contract Status Reason of the Order entity.
Found Business Rules with Scope: Entity there.
These can't be deleted "The process is part of a managed solution and cannot be individually deleted. Uninstall the parent solution to remove the process."
Deactivating them doesn't change anything.
Changing the Scope to a form and republishing and / or deactivating them again doesn't change anything.
I deleted all SDK Message Processing Steps found for Order with name "Project Service ..." from Default Solution Explorer: doesn't change anything.
Clicking on "Remove Active Customizations" on screen below throws error: "Unable to remove active customizations."
=> How the hack can I get rid of these dependencies?
