Have you been working with Power BI for a while? Then it is time to take the next step with your data modeling skills!

You might have heard about Power BI composite models. But in order to implement them successfully, it is important to understand the different storage modes that Power BI has. This is key for a successful implementation and also understand the possible dangers of the storage mode behaviors.

More over, let's also talk Calculation groups! You might have been creating numerous calculations in the past for year to date, quarter to date and many other common patterns. With Calculation Groups you can limit the number of redundant measures by creating a common expression parts in a group, that can be applied on top of multiple measures.

And finally, we will combine the two together. Dealing with calculation groups in composite models. Cause there are some key-elements you have to keep in mind. Potentially this combination can lead to wrong results, if you do not understand the behavior of the remote and local engine and with that dealing with wholesale and non-wholesale queries.

During this demo-rich session I will take you on a tour through all above mentioned features and cases, and explain them one by one. So that after this session you will be able to;
- Understand and explain different types of storage modes in Power BI
- Combine DirectQuery and import storage modes in a composite model
- Successfully implement calculation groups
- Understand calculation groups in composite models and their behavior
