In this lesson, you will create hierarchies. Hierarchies are groups of columns arranged in levels; for example, a Geography hierarchy might have sub-levels for Country, State, County, and City. Hierarchies can appear separate from other columns in a reporting client application field list, making them easier for client users to navigate and include in a report. To learn more, see Hierarchies.
To create hierarchies, you'll use the model designer in Diagram View. Creating and managing hierarchies is not supported in Data View.

This topic is part of a tabular modeling tutorial, which should be completed in order. Before performing the tasks in this lesson, you should have completed the previous lesson: Lesson 8: Create Perspectives.
To create a Category hierarchy in the DimProduct table
In the model designer (diagram view), right-click the DimProduct table > Create Hierarchy. A new hierarchy appears at the bottom of the table window. Rename the hierarchy Category.
Click and drag the ProductCategoryName column to the new Category hierarchy.
In the Category hierarchy, right-click the ProductCategoryName > Rename, and then type Category.
Renaming a column in a hierarchy does not rename that column in the table. A column in a hierarchy is just a representation of the column in the table.
Click and drag the ProductSubcategoryName column to the Category hierarchy. Rename it Subcategory.
Right-click the ModelName column > Add to hierarchy, and then select Category. Do the same for EnglishProductName. Rename these columns in the hierarchy Model and Product.
To create hierarchies in the DimDate table
In the DimDate table, create a new hierarchy named Calendar.
Add the following columns in-order:
In the DimDate table, create a Fiscal hierarchy. Include the following columns:
Finally, in the DimDate table, create a ProductionCalendar hierarchy. Include the following columns:
