Lables in DI studio

[Babloo]

I'm developing the DI job to convert the SAS dataset to the CSV file in DI Studio 4.21. I want to add the label for the following variables as follows, so that my output CSV file has the field names like cdnumpol, feemisio and produkt

t11.POLICY_ID as cdnumpol, 
t1.CREATED_DTTM as feemisio,
t2.PRODUCT_NAME as produkt

Could someone of you tell me how to accomplish this?Adding the description to those variables didn't worked though.

You are changing column names, not SAS labels with that code.

please also share your CSV file generation code so we can see what's going on.

Could you please tell me how to change the column names in DI studio?

I don't have code for CSV file generation.

Some confusion here.
It seems from that code snippet you already change the column names.
Labels are reflected in column descriptions.

I didn't changed the column names. I want to change it as I mentioned in my
initial post.

Then use something like the Extract Transformation and map your source table into a target table or view (green table) with the new column names and then use this table/view as input to the File Writer.
