Today I was helping a customer with a problem that seemed quite simple on the surface. She had a data table containing historical customer sales orders (each customer has many orders on different dates). The objective was to filter this table in Power Query and just load one record for each customer – the one that was the last order date. To illustrate the problem more clearly, I have adapted the scenario using the Adventure Works database.
I was trying to clean up my hard disk drive on my PC the other day. I use a program called WinDirStat to show me graphically what is taking space (as an aside, this is great software and you can download it here). After running the software I noticed that I had stored photos from my phone in a few different places. Each of the 3 sections below are images from my phone stored in different locations.
In a year’s time there will be a great opportunity for someone to present a session on “Power BI Development Best Practices” at the PASS Summit. Before then, we will all have to work out what those best practices actually are – probably the hard way. With that in mind, here’s a suggestion for one good practice that came out of a conversation at this year’s PASS Summit (thank you Prathy).
