SapBusinessWarehouse.Cubes

Understanding SapBusinessWarehouse.Cubes

Before we dive into the M code, it’s important to understand what SapBusinessWarehouse.Cubes is and what it does. This function is used in Power Query, which is a data connection and transformation tool that allows users to connect to various data sources, including SAP Business Warehouse (BW). In particular, SapBusinessWarehouse.Cubes is used to retrieve data from BW cubes.

A BW cube is essentially a data structure that stores multidimensional data in a way that is optimized for querying. By using SapBusinessWarehouse.Cubes in Power Query, users can easily access data from these cubes and use it in their analysis.

The M Code Behind SapBusinessWarehouse.Cubes

The M code behind SapBusinessWarehouse.Cubes is what makes it possible to retrieve data from BW cubes. When using this function, the M code is automatically generated by Power Query. However, it’s still helpful to have an understanding of what the code is doing and how it works.

At a high level, the M code for SapBusinessWarehouse.Cubes is responsible for connecting to the BW system, retrieving data from the specified cube, and transforming that data into a format that can be used in Power Query. Let’s take a closer look at each of these steps.

Connecting to the BW System

To connect to the BW system, the M code needs to know the system’s hostname, client ID, system number, and other connection details. These values are typically provided by the user when configuring the connection.

Once the connection details are known, the M code uses the SAP NetWeaver RFC SDK to establish a connection to the BW system. This SDK provides a set of libraries and APIs that allow programs to communicate with SAP systems.

Retrieving Data from the Cube

After connecting to the BW system, the M code needs to retrieve data from the specified cube. To do this, it uses the SAP Business Warehouse Provider for Power Query. This provider is essentially a set of functions that allow Power Query to interact with BW cubes.

SapBusinessWarehouse.Cubes specifically uses the function BW.Cube, which takes the name of the cube and other parameters as input. This function returns a table that contains the data from the cube.

Transforming the Data

Once the data has been retrieved from the cube, the M code needs to transform it into a format that can be used in Power Query. This typically involves converting data types, renaming columns, and performing other data cleaning operations.

The specific transformations that are applied will depend on the needs of the user and the data being retrieved. However, Power Query provides a wide range of tools and functions that make it easy to perform these transformations.

In conclusion, the M code behind the Power Query M function SapBusinessWarehouse.Cubes is responsible for connecting to the BW system, retrieving data from the specified cube, and transforming that data into a format that can be used in Power Query. By understanding how this code works, users can better leverage this function and make the most of their data analysis efforts.
