Creating a Selection Tree from Selection Tree Component
To create a Selection Tree from individual columns, follow the steps below:
1. Drag a Selection Tree component from the Component tree onto the Viewsheet grid. This creates an empty Selection Tree element.
You can also drag-and-drop columns directly onto a Selection Tree element. Each new column you add is placed at the innermost level of the hierarchy.
2. Right-click the Selection Tree, and select 'Properties' from the context menu. This opens the 'Selection Tree Properties' dialog box.
3. Select the Data tab.
4. At the top of the dialog box, select the 'Columns' option.

5. In the 'Table' menu, expand the desired Data Block to reveal its columns, or expand a cube dimension to reveal its levels.

6. Select the column or level that you want to be the outer-most level of the Selection Tree hierarchy.
To add all columns or levels from a Data Block or cube dimension, select the desired Data Block or dimension, and click 'Add'.
7. Click 'Add'. This adds the column or level to the 'Level' list.
8. Repeat to add all desired levels of the hierarchy. To change the hierarchy ordering, use the 'Move Down' and 'Move Up' buttons. The order from top to bottom represents the nesting order of the Selection Tree, from outer to inner.

9. Click 'OK' to close the dialog box.
The Selection Tree is now populated based on the selected columns or dimension levels. The inner levels of the hierarchy show only the unique items compatible with corresponding outer level data. For example, the companies nested within the outer-level 'CA' node are only those companies whose corresponding state is CA.
