Power BI Page Drillthrough

The September release of Power BI Desktop adds two very useful features: drilling through another page and explain increase/decrease. SSRS practitioners might find “page drillthrough” similar to SSRS actions. However, instead of navigating to another report, it allows the user to navigate to another page within the same report (at least for now cross-report drillthrough […]

Deploying and Processing Azure AS

In the “Processing Tabular from Exotic Clients” blog, I said that if you Azure AS model retrieves data from an Azure database, such as Azure SQL Database, it should also be located in the same Azure data center for faster processing and to avoid data transfer fees between data centers. Let’s elaborate a bit on […]

Prologika Newsletter Fall 2017

Business Performance Management   As I’m writing this newsletter, Florida and Georgia (I live in Atlanta, GA) are in the midst of planning for hurricane Irma, which is expected to be one of the most powerful Atlantic Ocean hurricanes in recorded history. I hope that this won’t be the case and we don’t have to […]

Processing Tabular from Exotic Clients

Processing Tabular models from SSMS or .NET client apps is pretty straightforward. For example, you can connect with SSMS and issue processing commands through the UI or via TMSL. You can also use custom apps with Tabular Object Model (TOM) and you can send XMLA commands directly if you have an app perhaps that’s already […]

Power BI What-if Analysis

Veteran Excel users might have used the Excel What-if feature that let you try several different sets of values in one or more formulas to explore various outcomes (scenarios). The August release of Power BI Desktop introduces a similar feature. You start by defining a What If parameter from the Modeling tab. Don’t confuse the […]

Power BI vs. Pyramid

I’ve never thought I’d see this one coming but today I got a marketing email from Pyramid Analytics (previously an ardent Microsoft partner) citing a head-to-head comparison with Power BI. Et tu, Brute? “Let’s start with a clear pricing model – one that doesn’t require an online calculator to figure out annual costs. Let’s add […]

Creating PBI Detail Reports

Related to the previous blog, let’s show how to create a detail report in Power BI that mimics an Excel PivotTable report in a flattened layout. Consider the report below. To create it, use the Matrix visual and add the necessary fields to the Rows bucket and measures to the Values bucket. By default and […]

Considerations for Detail Reports

Nobody likes watching a report spinny. Interactive detail reports that perform well from an Analysis Services semantic layer have been the bane of my BI career. A “detail report” is a report that requests data at a lower level, e.g. policy in the insurance business, customer in Sales, etc. A detail report typically has many […]

MVP For 14 Years!

Got awarded for Microsoft Most Valuable Professional (MVP) – Data Platform again. This will make my 14th consecutive year to be recognized by Microsoft for my expertise and contributions to the community! Apparently, it became difficult (or not cost effective) to count years, so the ring is for 2017-2018 but the tower doesn’t lie.
