    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.  We currently have a dataset that comes from Solver.  We then have reports that have been built off of a live connection to this dataset.  However, when we added columns in Solver, they showed up in the dataset but not in any reports that had already been built.  Does this mean to get these additional columns we would need to recreate these reports off the refreshed dataset?  This seems like a flaw in PowerBI.
