Nice 👍

Just for my understanding of the visibility. This works because the filter itself restricts visibility of the work packages. The descendants itself are not restricted, and queries for.

openproject/modules/reporting/app/models/cost_query/filter/work_package_id.rb

Lines 40 to 46 in 3eed62c

	def self.available_values(*)
	WorkPackage
	.where(project_id: Project.allowed_to(User.current, :view_work_packages))
	.order(:id)
	.pluck(:id, :subject)
	.map { |id, subject| [text_for_tuple(id, subject), id] }
	end
