Select the Employee dimension table and click Next.
Select the Employee_ID in the member key list, Supervisor_ID in the Parent Key List, and Full_Name in the Member Name list. Then click Next.
Click Next to skip the Advanced options screen. Type Employee as the dimension name, clear the check box that allows you to share the dimension and click Finish.
Click the Data tab to see the Data Pane and drag the employee dimension down to the row area, replacing the existing dimension. The cube will display the sample data because it hasn’t been processed and the dimension members will be visible.
Expand the members to see the entire employee hierarchy.
In a parent child dimension there are values in the fact table both at the leaf level and at the parent level. Before processing the cube it is important to change the property of the dimension.
In the cube tree, select the Employee dimension and switch to Advanced tab of the properties window. A drop down list for the Members with the Data Property is displayed. There are three values: Leaf Members only(default); Non-Leaf Data Hidden and Non-Leaf Visible. Select the third option so that a comparison can be made on the sales figures.

The data pane refreshes to include new members for the supervisor data. The new member names are in parentheses. Since the total rows for the supervisor clearly include the word “Total”, the user may want to simply display the employee name for the new data fields. The template for displaying the new member name can be changed.
Clear the Data Member caption Template property and press enter.
