Overdue

Hi, 

According to your description, I can roughly understand your requirement, I think you can try this measure to apply as the conditional format for the column [Completed data] to achieve your requirement:

This is the test data I used:

Due Date = 'Table'[Date Received]+3

Then create a measure like this:

Color =

IF(

    MAX('Table'[Date completed])<>BLANK(),

    IF(MAX('Table'[Date completed])>MAX('Table'[Due Date]),"Red","White"),

    "Red")

Then you can set the conditional format for the field [Completed data] like this:

And you can get what you want, like this:

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
