How to subtract one date column from another date column as a measure?

[Anonymous]

I have two columns in the same table that are both date columns. I want to subtract one column from the other to measure the days between the dates.

Using the below example row one would be 01/21/2020 - 01/02/20 = 19 days

I'm assuming creating  a measure is the best approach...not sure how to do this.

You can use a column like:

Column = ([Act Good Issue Date] - [Created On (PO)]) * 1.
