![]() ![]() If tables from the same data source connection are imported at separate times, any relationships between those tables will not be created and must be created manually. ![]() If any of the relationships in the table above are missing, verify that your model includes the following tables: DimCustomer, DimDate, DimGeography, DimProduct, DimProductCategory, DimProductSubcategory, and FactInternetSales. ![]() Use the model designer in diagram view, or the Manage Relationships dialog box, to verify the following relationships were created when each of the tables were imported from the AdventureWorksDW database: ActiveĭimProductSubcategory The Manage Relationships dialog box show the relationships that were automatically created when you imported data. Right-click Relationships in Tabular Model Explorer, and then click Manage Relationships. In addition to using the model designer in diagram view, you can also use the Manage Relationships dialog box to show the relationships between all tables in a table format. The relationship's properties now also appear in the Properties window. This show these are the columns used in the relationship. Notice the GeographyKey column in the DimCustomer table and the GeographyKey column in the DimGeography table now both each appear within a box. The solid line between these two tables show this relationship is active, that is, it is used by default when calculating DAX formulas. To view all of the columns in a particular table, click, and drag on a table edge to expand or make it smaller.Ĭlick the solid line between the DimCustomer table and the DimGeography table. Moving tables does not affect the relationships already between the tables. ![]() You can also click, and drag tables to different locations, bringing tables closer together, or putting them in a particular order. Use the minimap controls in the lower-right corner of the model designer to adjust the view to include as many of the tables as possible. The lines between tables indicate the relationships that were automatically created when you imported the data. The model designer now appears in Diagram View, a graphical format displaying all of the tables you imported with lines between them. To review existing relationshipsĬlick the Model menu > Model View > Diagram View. For this tutorial, you will also add three new relationships. However, before you proceed with authoring your model you should verify those relationships between tables were created properly. Generally, when you import data from a relational source, existing relationships are automatically imported together with the data. When you imported data by using the Table Import Wizard, you got seven tables from the AdventureWorksDW database. Review existing relationships and add new relationships Before performing the tasks in this lesson, you should have completed the previous lesson: Lesson 3: Mark as Date Table. This topic is part of a tabular modeling tutorial, which should be completed in order. To learn more, see Relationships.Įstimated time to complete this lesson: 10 minutes Prerequisites For example, the DimProduct table and the DimProductSubcategory table have a relationship based on the fact that each product belongs to a subcategory. A relationship is a connection between two tables that establishes how the data in those tables should be correlated. In this lesson, you will verify the relationships that were created automatically when you imported data and add new relationships between different tables.
