Hi all,
I had a question about the following, I want to format a column like this:
12303213 --> 123_3213
123056453 --> 123_56453
12309801 --> 123_9801
1230648112 --> 123_648112
So basically I want to change the 4th character to a "_" the length values in the column can be different like shown above. I guess this has to be done using the FORMAT() function but I could'nt figure out how to write the DAX code for it.

I would acutally use the REPLACE function:
