Reading the Report

The Object Usage Report has two sections: Where {Object} is used in the schedule and Objects that reference {object}.

Where {object} is used in the schedule shows each occurrence of the object in the study’s schedule. Note that this section is blank for Event Groups, as these are the highest in the hierarchy. Objects that reference {object} shows all objects that reference the chosen object in a hierarchical tree view.

The page will refresh as new objects and references are added to the Study.

You can collapse and expand parent objects to show their children. Click the Expand () and Collapse () buttons to do so.
