Course Overview

In the First section of this course you will refresh the fundamentals of how DAX works.  as this section is a refresher section we will work through example rather fast.. We will discuss Row context and Filter context, ALL, FILTER, RELATEDTABLE, CALCULATE, EARLIER, Relationships and much more.

The aim of section 2 is to introduce you to some DAX functions that we will be working with in more detail later in this course.  Many of the functions and expressions we will use in this section allow you alter or amend how totals and subtotals are shown. Functions covered will include ISFILTERED, ISCROSSFILTERED, ALLSELECTED, HASONEVALUE and SELECTEDVALUES

In Section 3 we will look in dept at CALCULATE and Contest Transition.  You will learn when to use FILTER inside CALCULATE and also when it is useful to combine CALCULATE and VALUES.

Section 4 is packed with Case Studies.  We will look at different problems and the solutions.  The first case study will focus on parent-child-hierarchy and include functions such as PATH and PATHLENGHT.  The second case study will look at different Moving Averages using EARLIER, FILTER, VALUES and AVERAGE.  In the third case study we will look at the use of Iterator functions over different granularities.

Finally you will learn about about advanced relationships.  We will look at BI Directional Filters and the use of USERELATIONSHIP

Each section of this course contains a folder to download. The folder contains the examples shown in the course and also activities for you to complete. These Activities are of utmost importance.  When it comes to learning DAX, practice is a must.
