How to Add Data Fields in Power BI

Power BI provides various options to add data fields to your reports and visuals. By adding data fields, you can create meaningful representations of your data and perform powerful analysis. Let’s explore the different methods with examples.

Method 1: Adding Data Fields through the Fields pane

1. Open your Power BI report or create a new one.
2. On the right side of the Power BI window, click on the “Fields” pane.
3. In the Fields pane, you will see a list of available data tables and their fields. Expand the desired table or hierarchy to view the individual fields.
4. To add a data field, simply drag and drop it onto the canvas or onto a specific visual.

Example:

Let’s say you have a “Sales” table with fields like “Product”, “Quantity”, and “Amount”. To add the “Product” field to a bar chart, follow these steps:

1. Open the Power BI report and access the “Fields” pane.
2. Expand the “Sales” table to view its fields.
3. Drag and drop the “Product” field onto the bar chart visual.

Method 2: Adding Data Fields using the Modeling tab

2. In the top menu, click on the “Modeling” tab.
3. In the “Calculations” group, click on “New Column” or “New Measure” based on your requirements.
4. In the formula bar, enter the desired logic and calculations for the new data field.
5. Click on “Apply” to save the new data field.

Example:

Let’s say you want to add a calculated field called “Total Revenue” to your report. To do this, follow these steps:

1. Open the Power BI report and navigate to the “Modeling” tab.
2. Click on “New Column” in the “Calculations” group.

4. During the data import process, you can perform data transformations and create new columns or measures using the Power Query Editor in Power BI.
5. Click on “Close & Apply” to load the data and apply the transformations.

Example:

Let’s say you have an Excel file containing sales data. To add a new calculated column called “Profit” based on existing columns, follow these steps:

1. Open the Power BI report and click on “Get Data” in the Home tab.
2. Select the Excel file as the data source and connect to it.
3. In the Power Query Editor, select the desired table and click on “Add Column” in the Home tab.
