Cube functions can interact with the Data Model in Power Pivot.Once you have an external data connection, you can use the connection properties to point to another database table or query. Yet Cube Functions in Excel are formulas that allow users to retrieve data from certain kinds of sources. And so traditional Excel formulas canвЂ™t retrieve the Data from the Data Model. That means that there are no cells available on the worksheet for traditional Excel formulas to reference. Once again though, if one wanted to use an OLAP Cube in a Connection it required availability of an Analysis Services Cube of data.Data residing in Power PivotвЂ™s Data Model, is not directly visible in the worksheet. In Excel 2007 (and now 2010) the CUBE functions became native to Excel (as opposed to available through an Add-In) and were integrated with the new Connection object within the program.

Cube functions on the other hand reference members and get values from the data cube. The definition of a measure resides in a so called Measure and is saved as part of the Data Model. The DAX language is a necessary component to perform calculations on your dataset. In fact, thereвЂ™s a beautiful collaboration between DAX (measures) and Cube functinos. How is it that Cube functions retrieve data from the Data Model in the Excel Worksheet?вЂњ ThereвЂ™s no need to worry.

Cube functions will never replace the DAX formula language. It is through this portal that the Excel user gains access to the Data Model data. You could say that Cube formulas are the portal between the Data Model and the Excel Worksheet.

DownloadTake a moment to examine the formulas. Data SetupTo follow along you can use this example file. How to use Cube FunctionsThe easiest way to get started with Cube functions is by using a Pivot Table that uses the Data Model as its Data Source. Since I donвЂ™t want to bore you by too much theory, letвЂ™s finally get our hands dirty.

In this case the column Day Name from the Calendar table filtered on Friday. The green marked cells are CUBEMEMBER formulas that contain references to a single member of the data model. The orange marked cell is a CUBEMEMBER formula that contains a cell reference to the DAX Measure called Total Sales. The newly created cube functions are CUBEMEMBER() and CUBEVALUE().

Other Cube function s exist, yet to get started these two are the most important ones to master. Without adjustments, the CUBEVALUE formula can easily be copied down.The functions CUBEMEMBER and CUBEVALUE play a central role in retrieving data from the Data Model. It always references the Total Sales Measure, and the cube member to the left of it, referencing the day of the week. Notice that the CUBEVALUE formula is the same for each value. The numbers are CUBEVALUE formulas that in this example reference two CUBEMEMBER formulas. Yet it references all the values, instead of filtering a single day.

The first argument is the connection. If the value does not exist, the formula will return #N/A.The syntax of a CUBEMEMBER formula consists of 3 arguments: CUBEMEMBER( connection, member_expression, caption) The formula verifies whether the specified member exists in the data model/cube and if it does it will return this member. It determines what part of the data cube your CUBEVALUE formula returns.

The third argument Caption is optional. This argument either slices the data cube through certain members, or indicates a DAX Measure. The Member_Expression comes second. Excel automatically creates it, and generally for me this is вЂњThisWorkbookDataModelвЂќ.

Examples: CUBEVALUEThe CUBEVALUEfunction combines the CUBEMEMBER functions it references. Total Sales in the Product Sales table). The value Friday in column Day Name in the Calendar Table) вЂ“ Measures (e.g. Day Name or Year in a Calendar Table) вЂ“ Column References filtered on a single value (e.g. This argument is very flexible and can contain static text, cell references or formulas.Some common Cube members are: вЂ“ Column References (e.g.

At the intersection of the referenced CUBEMEMBERS, the CUBEVALUE formula performs the DAX Measure. And second it depends on the DAX Measure that indicates what calculation it should perform. ItвЂ™s like filtering down your data set. First of all it depends on CUBEMEMBER functions that slice the Data Model down to specified members. Its value depends on two elements. You can see it as an instruction on how to retrieve data from the Data Model.

Member expressions that come after the first one are optional. Member Expressions are references to CUBEMEMBER functions. The Connection refers to the Data Model Name.
