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
