Overview of this book

DAX provides an extra edge by extracting key information from the data that is already present in your model. Filled with examples of practical, real-world calculations geared toward business metrics and key performance indicators, this cookbook features solutions that you can apply for your own business analysis needs. You'll learn to write various DAX expressions and functions to understand how DAX queries work. The book also covers sections on dates, time, and duration to help you deal with working days, time zones, and shifts. You'll then discover how to manipulate text and numbers to create dynamic titles and ranks, and deal with measure totals. Later, you'll explore common business metrics for finance, customers, employees, and projects. The book will also show you how to implement common industry metrics such as days of supply, mean time between failure, order cycle time and overall equipment effectiveness. In the concluding chapters, you'll learn to apply statistical formulas for covariance, kurtosis, and skewness. Finally, you'll explore advanced DAX patterns for interpolation, inverse aggregators, inverse slicers, and even forecasting with a deseasonalized correlation coefficient. By the end of this book, you'll have the skills you need to use DAX's functionality and flexibility in business intelligence and data analytics.

Comparing budgets and actuals

Budgets and actuals for businesses are generally reported at two different calendar scales. For example, budgets are often presented at the month or year scale, while actuals are generally presented on the day scale. Because of these two different scales, it can be difficult to track daily revenue versus budget to determine whether a particular month or year is on track to meet or exceed the budget for that month or year.

This recipe demonstrates how to rationalize and compare revenue figures that are provided at two different time scales by demonstrating how to compare actual revenue provided at a daily scale with budget numbers provided at a monthly scale.
