Combining two dimensions into one

[kaylaramsey2]

Hello,

I am trying to combine two dimensions into one.  I need every result of the first column but only one specific result of the second column.

I tried this:

=pick(match($Field, 'column1', 'column2'), column1, only({<column2 = {'12345'}>} column2))

However this keeps giving me an error.  Is there another way to combine these two columns?

Have you considered solving this by creating the logic in your script?

Load

column1, 

column2,

If(column2=12345,12345,Column2) as Column12

From source;

This would probably work.  I'd prefer it to go directly into the expression if it is possible.

Any thoughts?
