Calculated column based on values in other columns?

[tmitton]

I have four surveys feeding into a single Power BI dataset. The four surveys all have different questions, but are related to one another which is why I pulled them into a single data table. Since all of the questions are different, each questions gets its own column and if a column is blank that just means that the corresponding Survey was not completed for that row. 

I want to create a calculated column that will identify which survey was completed for that particular row of data. In my example below, if colulmn B contains a value, I want column A to return a value of "Survey #1". If column B does not contain data, I want it to look at columns C, D, and E, and whichever one has a value, tell me which Survey was completed. 

I recreated this in excel to try and provide a visual of what I'm trying to do in Power BI.

Hi @tmitton ,

Try this calculated column

Calculated column =
"Question#"
    & IF (
        [Qustion#1] = BLANK (),
        IF (
            [Qustion#2] = BLANK (),
            IF ( [Qustion#3] = BLANK (), IF ( [Qustion#4] = BLANK (), BLANK (), 4 ), 3 ),
            2
        ),
        1
    )

You can check more details from here.

@tmitton Try unpivoting your Question columns in Power Query. (B, C, D, E columns)
