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:
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:
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
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.
When trying to get the details for planner tasks, the following error-message appears:
Edit 5th May 2019: Unfortunately this method will not work in the Power BI service!
In my last 2 posts I’ve described a way to automatically validate attachments from incoming E-mails. Microsoft Flow would watch for incoming E-mails, that match certain criteria and move their attachments to a dedicated folder. Then it would trigger a refresh of a Power BI dataset, that has been designed to check for errors in those attachments. Data driven alerts in Power BI would indicate if there are errors and trigger a Flow that sends an E-mail back to the sender, informing him that his attachments didn’t meet the agreed criteria.
In this article I will now explain how not just a trigger about the existence of a faulty attachment could be passed back to Flow, but also the corresponding data itself. Therefore I write a query that exports data from Power BI to Flow. But watch out: This is not suitable for very big tables. I experienced timeouts at tables with 300k rows already. Read more
In Part 1 of this little series I described the core-Flow on how to automatically validate E-mail attachments with Flow and Power BI. It automatically sends an e-mail to a business partner who sent an attachment, that didn’t meet the agreed specifications:
But before going live with this Flow, you should consider the following aspects:
Sometimes I need to retrieve the textual representation of a type in Power Query and I’m using a fairly verbose function that I’ve stolen ages ago (I believe it was here: https://ssbi-blog.de/technical-topics-english/power-query-editor-using-notepad/ ) :
