Live Data Source - add columns?
hi, lk5683
When you use Live connection, you can not add columns or table, it can only create a report level measure. If you need to add columns, you need to do these in the datasource.
When connecting to SQL Server Analysis Services (SSAS), there is an option to either import data from, or connect live to, the selected data model. If you select import, then you define a query against that external SSAS source, and the data is imported as normal. If you select to connect live then there is no query defined, and the entire external model is shown in the field list. If you select DirectQuery, as visuals are built, queries are sent to the external SSAS source. However, unlike DirectQuery, there is no sense in which a new model is being created; in other words, it's not possible to define new calculated columns, hierarchies, relationships, and so on. Instead you are simply connecting directly to the external SSAS model.

I have a related question... I'm connecting live to an SSAS tabular model. I am also creating a few report level measures using the dax CALCULATE and FILTER functions. The measures appear to be working correctly. However, after the model refreshes, the report-level measures featured in Card visuals display an X instead of the measure. This can be corrected by hitting the refresh button. Why do the visuals fail to generate automatically after refresh, and what can be done to solve this issue so I don't have to hit the refresh button manually after each scheduled refresh (using connect live)?
