### Calculated Columns in Data Model

You can add new columns to your data models with calculated columns. You define the values in that column using the formulas from the data source.

### Measures and Column Analysis for the ContoSo Sales Sample

The measures and columns are both based on the same formulas, but they differ in how they are used. You can use measures in a visualization's Values area to calculate results. You use calculated columns as new Fields in the rows, axes, legends, and group areas of visualization.

**The Contoso Sales Sample** has sales data for both active and inactive stores. You want to make sure that active store sales are separated from inactive store sales in your report by creating an Active StoreName field. The sales for inactive stores will be grouped together in one line item called Inactive, while the active stores will appear with their full name.

The first argument for IF is a test of a store's status. You can type an opening brackets which list columns from the Stores table. Columns can be useful for your data.

### DAX Formulas for the Number of Shipments to Different Cities

The data you've already loaded into the model is what determines the calculated columns that are created in Report view or Data view. You can choose to add or remove values from two different columns in two different tables. Similar to excel formulas are the DAX formulas.

Many of the functions in excel are the same as in the DAX. ** Power BI Desktop** has functions that work over data interactively sliced or sorted in a report. You can change the formula for each row in a table in excel.

When you create a formula for a new column in Power BI, it will calculate a result for every row in the table. Jeff wants to create a report that shows the number of shipments to different cities. There are separate fields for city and state in Jeff's geography table.

Jeff wants the reports to show the values of the city and state on the same row. Jeff's geography table doesn't have the field that he wanted. Jeff can add it to the report canvas with the number of shipments.

### Calculating Columns in the FIELDS PANE

Columns are calculated when you first define them and during a dataset refresh. The per-unit profit of a product is calculated by subtracting the cost of the product from the price. The table name in the FIELDS PANE can be used to create a calculated column. You can use **the Power BI Query** Editor to create a column.

### Power BI: A New Look at the Data

The power behind Power BI involves creating new calculated columns and measures. They get or calculate the data in very different ways. You should be questioning the result if you do data analysis.

### Add New Columns to BI Model in Power Data and Report View

You can add **a Calculated Column** in Datand Report View or **a Custom Column** in Power Query Editor to add new data to a table already in your model in Power BI Desktop.

### Power BI and Models

Power BI has two important concepts to understand. They look the same, but there is a huge difference in how they work. A column is calculated at the report refresh level, while a measure is calculated at the query refresh level.

A column is created using a data model that is loading and consuming time and memory. A measure does not consume memory or disc space because it is calculated on the query's refresh time. A column is part of a model.
