Gilbert Quevauvilliers has a challenge:

In the blog post I am going to show you the steps that I took to get data from the XE.COM API which uses a username and password to log into the API

You might be thinking that I could put in the username and password when I used the Web Connector.

My challenge is that I wanted to create a function that I could pass through multiple currencies to the API. And in order to do that I wanted to store the details within the function.

Read on to see how Gilbert solves this.

Matt Masson has a helpful table:

I frequently refer to this table of Uri.Combine combinations, so thought it might be worthwhile to post.

Lazaros Viastikopoulos explains that finding the size of a Power BI file isn’t quite as easy as you’d think:

As you can see from the above screenshot, the size of the PBIX file is 1.2 MB (1,238 KB) by looking at the size in file explorer. Also, when we look at all the files we are ingesting into Power BI, the total size comes to 2.8 MB. However, when we ingest data into Power BI which is processed to memory, it can be bigger than the PBIX file size due to some compression that occurs and various other elements which again, are not displayed through the disk.

So, when we are getting various errors notifying us that our Power BI file is too large and we see that it is under the 1GB restriction on disk, it can leave us scratching our head. But, as I mentioned above due to compression and various other elements, once data is processed to memory it can be larger then what we see on disk, but still below the total size of the data source we are ingesting due to the compression.

Matthew Roche dives into Power BI’s enhanced compute engine:

I’ve been seeing more questions lately about the dataflows enhanced compute engine in Power BI. Although I published a video overview and although there is feature coverage in the Power BI documentation, there are a few questions that I haven’t seen readily answered online.

A lot of these questions can be phrased as “what happens when I turn on the enhanced compute engine for my Power BI Premium capacity?”

Most of my responses start with the phrase “it depends” – so let’s look at some of the factors the answer depends on.

Imke Feldmann walks us through separating data from report in Power BI:

The other day I discovered a neat way to split up an existing Power BI report into a Golden Dataset and a thin report file with very few adjustments to the existing setup. Imagine you have a Power BI report published for some time already in an app with row level security. Now, you want to create other reports from the dataset as well and decide it’s time to create a golden dataset from which multiple other thin reports can also be fed from as well. But ideally you want to keep your published app, that many users are working with already, unchanged.

There’s a way to do this and Imke shows us the way.

Paul Turley compares Power BI paginated and analytic reports:

This brings me to the subject of this post: Paginated and Analytic reports.

Before we had Power BI, we had Reporting Services. When the focus of my career and consulting practice became Business Intelligence – fifteen to about five years ago – most of the “BI reports” I created were in SQL Server Reporting Services (SSRS). We could create a variety of charts and reports that allowed users to drill-down from summary to details. We could create reports that allowed a user to drill-through, from one record or report item to another report that presented more details. With a little creativity, we could create reports that allowed users to click items that would filter other items on the same report. It took some work and time to create these interactive “drill-through-to-self” reports. Today, after transforming data into the right format for a tabular data model, this type of interactive functionality just magically happens in Power BI with very little report design effort. But, Power BI is primarily a tool for analyst users to create their own reports and to get answers to business questions rather than for IT developers to create reports that print or export perfectly to a PDF or Excel.

For now, Paul is asking for thoughts and questions with the promise that there will be an update to the post. So stop on by and ask a question or two.
