Recently switching from 10.5 to 10.6, some custom PowerBI reports stopped working seemingly due to database changes.  Connecting with ODBC, I can see that while the accountci table used to be tied to the accountdefinition table by the ciid value on each, I can see that there is no longer a ciid column in the accountdefinition table. 

I suppose my question is how are the accountdefinition and accountci tables tied together at this point?  If there's a particular table that ties the two together matching a key value from accountdefinition to the ciid in the accountci table, I can't find it. 

Can anyone point me in the right direction?
