Steps taken to create an OLAP Cube from raw data in Power BI include:

1. Importing the raw data into Power BI. data can be in form of excel files, SQL databases, or cloud-based services.

2. Once the data is imported, it is transformed, by formatting in the way the user prefers. This can be done by filtering, sorting, grouping, and joining data.

3. After the data has been transformed, A data model can be created in Power BI by defining relationships between tables and creating calculated columns or measures. This step is essential for creating an OLAP cube, as it defines the structure and hierarchy of the cube.

4. Once the data model is defined, you can use the Analysis Services Connector in Power BI to create the OLAP cube by defining the cube's dimensions, hierarchies, and measures, and specifying how the cube should aggregate and summarize data.

5. After creating the OLAP cube, you can test it by querying the data and analyzing the results. You may need to refine the cube's structure or aggregation logic based on your analysis, to ensure that it provides meaningful insights into the data.

6. Once you are satisfied with the OLAP cube, you can publish it to a Power BI workspace or a server, and share it with other users. The OLAP cube can be accessed through Power BI reports, Excel, or other OLAP client tools, allowing users to perform multidimensional analysis on the data.
