Q&A in Power BI Desktop

Natural queries (aka Q&A) has been a prominent feature since Power BI Service existed. Wouldn’t be nice to do the same in the Power BI Desktop? You can, but make sure to enable first Q&A from File, Options and Settings, Options (“Preview features”) tab because it’s currently a preview feature. Once you do this and […]

SSRS Multivalue Parameters in DAX

Déjà vu today with a twist. SSRS multivalue parameters in SSAS reports but this time in DAX. Now that SSAS Designer supports DAX queries, we should be able to do everything we were able to do in MDX, right? Unfortunately, as you will quickly discover, Microsoft “forgot” about multivalue parameters when working on the DAX […]

Power BI Writeback

One of the Power BI most prominent strengths is that it’s a part of the much broader Microsoft Data Platform that spans various on-premises and cloud offerings for data storage, processing, and analysis. After the integration with Visio, Power BI just took another leap forward with the introduction of the PowerApps custom visual. Use this […]

Applied Power BI Book (3rd Edition)

I’m excited to announce the third edition of my Applied Microsoft Power BI book! When the original book was published  in January 2016, it was the first Power BI book at that time. Since then, I helped many companies adopt or transition to Power BI, and taught hundreds of students. It’s been a great experience […]

Prologika Newsletter Winter 2017

Sharing Reports with External Users Happy Holidays! I hope you’re enjoying this special time of the year – time for sharing and giving. Speaking of sharing, how does your company share BI artifacts with your B2B or B2C partners? Do you still send Excel spreadsheets or embed canned SSRS reports? If so, Power BI offers […]

Field Description Support in Power BI Desktop

I’m a big fan of self-documented semantic models. Business users have a hard time getting their way around complex models and descriptions can go a long explaining the purpose of metadata. After waiting for years for Excel to support field descriptions (the wait is still on), the December update of Power BI Desktop now supports […]

Power BI vs. Tableau (Part 3)

Feeling the heat, Tableau has come up with an updated Power BI vs. Tableau battle card as one of my clients pointed out. This time designed as a video. I guess the previous “10 Ways Power BI Falls Short” slide deck, which I discussed in the part 1 and part 2 of my “Power BI […]

Hey Cortana, where is Power BI data?

A Power BI presentation is rarely complete if someone doesn’t ask me to demonstrate the Cortana integration. However, unlike everything else in Power BI that gains features in time, in my opinion the Cortana experience has lost some value. Previously, you could ask natural questions in Cortana across datasets, just like you can use the […]
