If tree limits lists apply query limits, you must select the queries and data model sections to which the query limits apply.
To select queries and data model sections:
In Interactive Reporting Studio, open a dashboard that contains the Tree component.
From Sections, select HYSL Queries and Datamodels.
Move sections between Available Sections and Sections to Process by clicking
and 
.Click Apply.
From this point, when Process is clicked on a tree limits list to apply query limits, the limits are applied to the selected query and data model sections.
