Several columns add into one column

[Surname]

Hi there, 

I have one question to data blending: 

My Data Source is Salesforce. I chose one Table and three Fields: 

And this is my Results as an output: 

I have three colums (becaus of three fields). 

My question is how can I assemble all three colums into one column?  

Thank you in advance!

You can use a Formula tool to create a new Output Field and concatenate the values. The expression would be (assuming the fields are all string): Code1+Code2+Code3.
