All about Power BI, Modelling, DAX and Microsoft BI
Usually I start my blog posts with an interesting question I got, this time we will do the reverse. I want to talk about a question that isn’t asked often enough: “Should I use DirectQuery?”. Read more
Just a quick post today. Power BI desktop has a feature to turn on the SSAS profile traces that allows you to see all the queries (DAX and SQL in DirectQuery mode) generated by the reports. I couldn’t find any documentation to turn it on so let’s take you through the steps here. Read more
A common questions I get is to change the connection string to from my report to SSAS after I move my Power BI desktop file into SSAS. It turns out this actually pretty simple as there is an API that allows you to copy and then bind the report to ANY dataset. Let’s walk through this. Read more
Another interesting question that came up recently is how to do currency conversion in Power BI. My colleague Jeffrey Wang had a very neat solution that I want to share more broadly. Read more
Another Power BI embedded blog post while I have a playground up and running. Often when you want to use SSAS with Power BI embedded you have a “authentication issue”. Power BI and SSAS both leverage AD so that means that any user you pass from Power BI to SSAS needs to be known in AD. Now that is great in enterprise scenario’s where this usually is the case (and even required) but for ISV’s... Read more
I have recently gotten this questions a few times so time to dust off my coding skills and get to work … the key question in both cases is how can I make sure I filter my report before any queries are being send to the underlying data source. When using Power BI embedded you can use Javascript to pass in a filter instead of using the Power BI UI. To test how this worked... Read more
Another interesting question I got this week kind of extends on the previous blog posts where I used disconnected slicers to filter data but this time instead of having the data already in the model the request was to allow to write a filter based on a comma separated list. So off we go again into the DAX rabbit hole Read more
I got an interesting request this week, to improve the usability of the tabular model they wanted to filter the dimension table to only contain the rows that have data in the fact table. That way the slicers and other filters will never have data where you don’t have any sales or any facts. Often this is taken care before loading the data by creating view or writing queries but in this case this would... Read more
