I found that there may be a caching issue or something related to the power bi ssas connector and ssas tabular model schema changes. The behavior I observed is that if I make a change to the tabular model (i.e. add new columns, measures, tables, etc.) Then go back to the web UI, it doesn’t show those changes. I tried selecting a different dataset and then going back to the changed dataset and it still doesn’t pick up the changes. I even tried refreshing the browser and closing and restarting the browser and the changes still don’t show. What I ended up doing was going to the server and stopping the ssas connector service and the restarting it and then when I go to the browser and select the dataset I see the changes. I was working through some training with several customers and didn’t have time to wait a long time to see if it eventually shows up (over the course of the things I tried I believe about 8-10 minutes elapsed before I restarted the service) Not sure if anyone has reported this
