Hi
According to your description, it seems that you want to create a drill down report to display Office 365 licensing data, right?
To create a drill down report, we need to place fields which contain hierarchy in Axis Property of the chart to enable drill down action. In your scenario, if you are using chart visual, you need to place both SKUID and Service Plans Status fields in the Axis property. For more information, please refer to this article: Drill down in a visualization in Power BI.
If you have any question, please feel free to ask.
Best Regards,
