Live connection to Dataset and calculated measure/column (?) based on one of the fields

[talsed]

Hi,

I am new to PBI so maybe I'm missing something here, but it should be quite simple  problem (hopefully :)). 

So I have a dataset which I am connected live to and I need to create a measure/column (?) based on one of the columns in the dataset.

For example: 

I have a column with "Country" value. 

I need to create a dynamic measure/column (?) to be based on that "Country" field with the following conditions:

IF ( Country = USA) then "USA" else "ROW"

So then in the report I will be able to use this new dynamic calculated measure/column (?) instead of original "Country" field. 

I understand that due to live connection, I have no ability to create a new column in the model (correct?). 

On the other hand, when I try to create a meassure, I am getting the error saying somwething like "you are asking to check multiple rows and not specific one, so the meassure cannot be created". 

It sounds like a simple task but I'm really stuck here and can't find any solution to it.

I have read in the forums about X-functions to produce row by row meassures but I don't find If X meassure. 

What am I missing? 

Thanks,

Hi  @talsed ,

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.
