Hello all,

I have an existing column

I want to add a null value to the head of this row 

Expected output

Merged.1
Null

3
3
4

5

Thanks in advance

You can create a null row in a text input and then union the two streams together and check the box at the bottom of the union configuration so that the text input data set comes first.
