- Power BI is a business intelligence tool that allows users to connect to multiple data sources, transform data, and create interactive reports and dashboards.
- Power BI helps users make data-driven decisions by exploring data and creating visualizations, as well as collaborating on projects by sharing reports and dashboards.
- Changing data sources for existing Power BI reports can be challenging when the data source location changes or when connecting to a different source, requiring manual updates of information like data location and connection strings.
- M code is the programming language used to transform and shape data in Power Query, and it can be used to change the data source for an existing report by replacing details with new ones for the desired source type.
- Steps to change the data source using M code include opening the Power BI report in Power BI Desktop, clicking Transform data, connecting to the new data source, confirming column names, clicking on Advanced Editor, and replacing the M code to reflect the new data source accurately.
