I am importing my CSV file into Power Bi. I have 6 columns that have milestone dates, starts and finishes. What I am trying to do is after I add a custom column I need to have a formula look at the start date to see if there is a value. If there is not grab the value from the finish column. Can someone help me with the formula please. The next formula is for Actual Start and Actual Finish. Neither one of those will have a date until the activity is started then finished. That formula would have to be multi conditional.
