The official Power BI documentation has similar advice to what’s shown in this dialog about what to do here, but what’s really going on?
The information in the “More details” section of the section dialog gives you a clue: in this case it’s resource governance. When you run a DAX query in Power BI it will always use a certain amount of memory; inefficient DAX calculations can cause a query to try to grab a lot of memory. In Power BI Desktop these queries may run successfully but be slow, but the Power BI Service can’t just let a query use as many resources as it wants (if it did, it may affect the performance of other queries being run by other users) so there is a resource governor that will kill queries that are too resource hungry. In the case of the visual above the query behind it tried to use more than 1GB of memory and was killed by the resource governor.
Read on to understand where these limits are and how you can modify them.
