[From Wrike] Using the Days Difference (DDIFF) function

Hi Community,

I hope everyone has been well. I will continue this week and next with two posts, one showing the use of a function and another a use case that builds upon it. We will start with the often-requested DDIFF function!

You might find this piece helpful if:
• You would like an easy way to hold assignees accountable based on dates
• You would like exposure to or experience in formula edit mode
The DDIFF function calculates the number of days difference between one date field and another. Imagine subtracting one date from another and getting the difference in days. You can use DDIFF with Task or Project Start and End/Due dates, any custom date field, and you can also compare to today's date.

The most common use case is to measure the number of days from a task's due date until today to help keep track of task deadlines. Let's build a widget that does this together.

Next, I will add a value, which will become the number of days that have passed since the task's due date.
Let's start with a DDIFF function containing the Task Due Date (days grouping) as both arguments. Press OK and you'll see that the column shows 0 for all tasks, which is what we would expect as the two dates are the same.

Now, let's add the magic. I'm going to surround the FIRST Task Due Date with a NOW function, which tells Wrike Analyze to ignore the actual value in the Task Due Date field and instead return the current date. Ensure both fields use a days grouping.

Save the function and rename it Days Late. You may have to scroll right in the widget depending on how wide your other columns are. You should see that:
• Some numbers are positive (today is later than the due date = LATE)
• Some numbers are negative (today is earlier than the due date = NOT LATE)
• Some numbers may be zero (today is the same as the due date = NOT LATE BUT DUE TODAY)

Taking this one step further, let's add conditional formatting to define levels of "late-ness" as a compliance metric. Let's say that this metric has 4 levels:
• Not late (<= 0 days late) is Green
• Less than 7 days late is Yellow,
• Less than 14 days late is Orange, and
• At least 14 days late is Red.

Finally, sort by the "late-ness" metric field and we're done!

----------------

Looking for even more challenges with this function? Stay tuned for my next post where we will build a more complex use case using the DDIFF function!

For another challenging exercise, replicate the above color chart but pair DDIFF with a CASE function to state the level of "late-ness" in defined gradations such as: 0 (not late), 1 (<7 days late), 2 (<14 days late), 3 (>= 14 days late). Hint: You will call DDIFF 4 times!

Best wishes growing with Wrike Analyze!
