I am having a very strange problem when trying to display data from as SSAS multidimensional cube in Power BI Desktop (and in report server). The issue occurs when data regarding NULL and åäö (swedish signs) are combined in a matrix visualisation. If the value in a cell of a column is NULL, the value in the following column on that row is not showing. It appears to be NULL as well. But that only occurs if the following column has a column name that includes å,ä or ö. If I rename the column name by excluding å,ä,ö the correct value is shown.
I have not yet understood why this is happening or how I can prevent it (without renaming all my dimension/attributes/measures) or even exactly when this issue occurs. Can someone out there help me to understand what is going on...? Or is it just a strange bug in the application?
