Is it possible to write back to data file in postman?

Question

While working with postman, data.someVariable returns data from within a csv file that can also be used as {{someVariable}} in uri/json.

This gives us the data for that variable from that row/iteration.

Is there a mechanism to write back to the data file by doing something like postman.setData('responseCode') = responseCode.

This would be really helpful to store response code in the data file and to record call wise details in same format as the input within csv.

There is no way to write back to data file in postman as of now .

However, you can populate that in your environment file at run time using

pm.environment.set("varname")

keep varname in such a way that you understand this is the variable you wanted to write back into data file.
