After exporting into Tableau, all items and subitems are combined into the Items table. Subitems can be distinguished by the value in the Parent ID field.
As you can see from the screenshot, items don’t have value in the Parent ID column, and all subitems have value in the form of parent ID.
To select items for a specific project, you can apply filters. To see subitems for a specific task, filter them by parent ID.
