How to replace null values in a column from another column

[ThenNumbersGuy]

I have a few null values in column A " Month (End Date)" and Column B ("Year (End Date)" that I want to replace with values from Column C (Month ("Approved Date)") and Column D ("Year (Approved Date)"). In excel I just need to do a =formula and done but not sure how to code it in DAX to do this. Does anyone know the answer?

You can do this in Power Query pretty easily by adding a custom column with the following code:

if
Month[End Date] = null then
Month [Approved Date] 
else
Month [End Date]

This will create a column that has no nulls and either the Month Approved Date or the Month End Date. You then can remove both the End Date and Approved date columns if you want.  

Just repeat for the Year End column

Hi,

Is there a solution for this same formula, but for direct query?

Many thanks
