However, you can write your own KPI calculations in Tableau. When connected to Microsoft Analysis Services, any KPI calculations defined in the cube are not available. You can, however, write a calculation that takes cube cell results and bins them. Aliases are not supported by Microsoft Analysis Services databases.īy default, the alias for every member of every dimension is initially defined to be the original member name.įor cube data sources, the Create Bin command is not available for measures. Talk to your database administrator to find out whether your database has aliases available. It may be possible to use Table Calculations to perform aggregation operations on the cell-level results from the cube in Tableau.Īliases for cube databases are created by the cube's designer and can be activated in Tableau by selecting the data source from the Data menu and then choosing Alias File.
Level of detail expressions, trend lines, forecasting, and clustering are not supported for cube data sources.Ĭube data sources are pre-aggregated and thus do not support aggregation functions, such as SUM(), AVG(), and CNT(). But actions in the views using the cube data sources will affect the view using the MySQL data source. Actions in the view using the MySQL data source won't affect the views using the cube data sources, and actions in the view for one cube data source won’t affect the other. With Microsoft Analysis Services connections, drill-down actions defined in the cube are not available in Tableau.Ĭube data sources do not accept actions from relational or other cube data sources.įor example, suppose you have a workbook with a view that uses a MySQL data source, a second view that uses cube data source A, and a third view that uses cube data source B. The following table details the differences. When you use a cube data source, not all Tableau features work the same as with relational data sources, or are even available.

For details, see How to Create a Calculated Member. A calculated member can be either a calculated measure, which is a new field in the data source just like a calculated field, or a calculated dimension member, which is a new member within an existing hierarchy.
With MDX calculated members, you can create more complex calculations and reference both measures and dimensions. MDX, which stands for Multidimensional Expressions, is a query language for OLAP databases. When working with a cube data source, you can create calculated members using MDX formulas instead of creating Tableau formulas.

The cube data sources supported in Tableau are Thus, cube data sources are not as flexible as relational data sources if the types of questions you need to ask were not anticipated by the original designer, or if they change after the cube was built. These definitions remain static until the cube is rebuilt. However, the reason for a cube's speed is that all its aggregations and hierarchies are pre-built.
What are cube data sources?Ī cube data source is a data source in which hierarchies and aggregations have been created by the cube's designer in advance.Ĭubes are very powerful and can return information very quickly, often much more quickly than a relational data source.

Note: Cube data sources are supported only for Tableau Desktop on Windows – not for the Mac. Talk to your database administrator to find out if this is an option. In many cases there are alternative approaches that you can use to compensate for the unavailability of these features with cube data sources, but you may also have the option to connect directly to a relational database that was used as the source for a cube data source. This topic describes these differences, and also identifies some Tableau features that are not available when you connect to a cube data source. Cube data sources (also known as multidimensional or OLAP data sources) have certain characteristics that differentiate them from relational data sources when you work with them in Tableau.
