Post No. #982 Custom Column in Power BI : - A custom column in Power BI is a new column created by applying formulas, calculations, or logic on existing columns. It allows you to modify and enhance your dataset within the Power Query Editor before loading the data into Power BI reports. - Unlike calculated columns, which are created in the Data Model using DAX, custom columns are created using Power Query M Language and provide more flexibility in data transformation.

Post No. #971 - A PPU per-user license provides the license holder with all of the capabilities of Power BI Pro plus access to most Premium capacity-based features. A Power BI PPU license unlocks access to extra of features, capabilities, and types of content that are only available with a paid license. - A capacity-based Premium license allows Pro or PPU users to create and save content in Premium capacity workspaces. They can then share that workspace with colleagues who have any license type. 

Post No. #970 You can use what-if parameters to run scenarios and scenario-type analysis on your data. What-if parameters are powerful additions to your Power BI semantic models and reports because they enable you to look at historical data to analyze potential outcomes if a different scenario had occurred.

Post No. #969 Important points about Power Query: - Connects to various data sources like Excel, SQL Server, SharePoint, and web APIs. - Allows you to transform data by filtering, sorting, grouping, pivoting, and merging datasets. - Offers tools for cleaning data, such as removing duplicates, filling missing values, and splitting/combining columns. - Provides a visual interface to apply transformations without needing to write code.

Post No. #968 Package refresh in Power BI : - This refresh synchronizes your Power BI Desktop file (PBIX) with the Power BI Service after publishing. - Ensures that any updates made to the file on your local system are reflected in the Power BI Service. - It does not refresh the data itself but updates metadata like relationships, measures, and calculated columns in the model.

Post No. #967 Use Power Pivot Features in Power BI: Modeling View: Go to the "Model" tab in Power BI Desktop to establish relationships, manage tables, and define hierarchies. DAX: Write DAX formulas in the "Modeling" or "Report" tab. Measures and Columns: Use the "Fields" pane to create measures or calculated columns. Data Transformations: Use Power Query (accessible via "Transform Data") to clean and shape the data.

Post No. #966 A data modeling technique where a single fact table is connected to multiple dimension tables, and these dimension tables are further normalized into sub-dimension tables is called snowflake schema.Star schema is a mature modeling approach widely adopted by relational data warehouses. It requires modelers to classify their model tables as either dimension or fact. All dimension tables directly connect to the fact table.

Post No. #965 Power BI's future looks bright with expected advancements - Better connections with Microsoft products and services. - Enhanced AI and machine learning features. - Improved interfaces and self-service options. - More robust real-time data processing. - Better tools for team collaboration. - Expanded data source integrations. - Enhanced mobile features for on-the-go access.
