The `CUBERANKEDMEMBER` function in Excel is used to retrieve a member from a set based on its rank. This function is particularly useful when working with OLAP cubes or Power Pivot data models, allowing you to sort and filter data easily. Here is a step-by-step guide on how to use this function:
Syntax
CUBERANKEDMEMBER(connection, set_expression, rank, )
Parameters
- Connection: This is the name of the connection to the data model or cube. You’ll typically refer to a connection you’ve established to an OLAP database or a Power Pivot model.
- Set_expression: This is a text expression that represents the set of members or tuples you want to retrieve data from. It is usually written in MDX (Multidimensional Expressions) format.
- Rank: The position in the set from which you want to retrieve the member. It’s a numeric value that specifies which member to return, sorted in natural order. For example, 1 would return the first member.
- Caption (optional): This is a text string for optional display purposes, providing a name for the result retrieved by the function.
Example
Suppose you have a connection named “SalesData” to an OLAP cube, and you want to retrieve the third highest selling product from the set of all products.
=CUBERANKEDMEMBER("SalesData", "[Products].Members", 3)
Steps to Use CUBERANKEDMEMBER
- Set Up the Connection: Make sure you have an existing connection to your data source, typically set up via Power Pivot or via external data connections.
- Understand MDX Syntax: You must be familiar with MDX or the structure of your data model to construct appropriate `set_expression`. In many cases, Excel can help build these if you’re using PivotTables.
- Determine the Rank: Decide which ranked member you need from the set. For instance, if you want the second highest value, `rank` would be 2.
- Optional Caption: Use the optional `caption` to name the result in your worksheet clearly for easy identification, though it’s not necessary for the function’s operation.
Considerations
- Error Handling: If the `rank` specified is larger than the number of members in the set, Excel will return a `#N/A` error.
- Dynamic Analysis: The `CUBERANKEDMEMBER` function can be particularly powerful when combined with other CUBE functions like `CUBEMEMBER` and `CUBEVALUE` for dynamic and interactive data analysis.
- Refresh Data: If your data source updates, remember to refresh the connection in Excel to ensure you’re working with the latest data points.
Using `CUBERANKEDMEMBER` effectively requires knowledge of your data source and some expertise with MDX or similar querying languages. Once mastered, it adds a flexible tool for data reporting and analysis.
