问题
I am using Power BI desktop client on Win Server 2012 R2 and Win Server 2016. Both of the instances freeze up once I start creating the relationship between the tables that I loaded.
I have updated desktop client to Feb 2019 release and March 2019 release, but still same results.
Also, some of the IDs in tables contain NULL value which is not handled very nicely in Power BI, anyone encountered this issue before? Any help or suggestion is much appreciated!
