Bug in Power BI R Scripts “package … was installed with different internals”

Today I spent many hours hunting an R-script error in Power BI and before Steph Locke came up with a solution for this, I came across a couple of posts and heard of other people, having the same problem. This blogpost is to make distribution of the solution a bit easier and to hopefully to help other folks with the same problem in the future.

The Problem

When running R-scripts in Power BI, I got all sorts of error-messages who all had one thing in common: They were complaining about one or more packages being installed by an R version with different internals. Read more

A new Table.ContainsAnywhere function for Power Query in Power BI and Excel

The native Table.Contains-function in Power Query tells you if one or more strings are included in one or more of its columns. But you have to be specific about which strings you search in which column. But what to do if you want to search a string in all of its columns instead? Use my new Table.ContainsAnywhere function.

Problem

In the native function, you have to pass in a record with search term and column name. So if you search for “blue” in column “Description”, your formula would look like so:

Table.Contains( YourTableName, [Description = "blue"] )

But that’s not what I want in this case. I want the formula to search through all columns within the table for the occurrence of “blue”.

Easy way to retrieve Teams data in Power BI via Flow (and other data from the Graph)

In a previous post I’ve described how to use a custom connector to retrieve data from the Microsoft Graph API. But this requires to register an App and adjusting the M-code in the connector itself requires some M-knowledge. So I thought it might be a good idea to share an alternative method to retrieve data from Teams for example, that works out-of-the-box. There are a couple of endpoints supported currently:

Query folding on JoinKind.Inner gotcha for Power BI and Power Query

If you query databases who support query folding, you’re probably very aware of every step you take and check if folding happens with every new step like so:

“View Native Query” shows folding query that’s send back to the server (if not greyed out)

Folding will (usually) happen as long as “View Native Query” isn’t greyed out.

So when doing an inner join on tables whithin the same database, I was a bit surprised to see this greyed out actually. As according to the literature, it should fold.

But guess what? After I expanded a column from it, the folding was back again: Read more

How to get more out of your Graph API custom connector in Power BI

The Graph API can deliver a huge amount of interesting data from your Microsoft 365-universe, but the Graph API custom connector for Power BI is not able to retrieve everything from it in its current shape. So I’ve modified it a bit to squeeze out a bit more of its sweet juice.

Problem

When trying to get the details for planner tasks, the following error-message appears:
