I've managed to create charts in Power BI using OData from a Mendix app, but only when representing associations as associated object id's (which makes sense to me). However, if I want to use many-to-many associations, it's only possible to expose them if the associations are represented as links. I haven't figured out how to relate the objects (like this) in Power BI. Has anyone been able to achieve this?
This issue was fixed in 7.21.0:
This should allow you to expose many-to-many associations.
