A bit of a light edition this week - no announcements other than the On-premises data gateway September 2023 release. So, onto the community articles. First of all, Alberto Ferrari has weighed up the number of ways you can Find products without sales by using DAX, Chris Webb has discussed how you can Keep Your Existing Power BI Data And Add New Data To It Using Fabric, offering a more robust solution to a previous post he wrote describing how to achieve incremental refresh without a backing relational store. And finally, Rick de Groot has written in detail about Understanding Recursion in Power Query using the Tower Of Hanoi puzzle as a fun demonstration.
