Automated RYG Balls
Hi,
I'm trying to add an automated RYG light column formula with the following function:
 Green = [Status] is either 1) "Resolved" or 2) [Status] is "Open" and [Due Date] is in the future
 Yellow = [Status] is "Open" and [Due Date] is in 14 days or less (including today)
 Red = [Status] is "Open" and [Due Date] is in the past
Can anyone assist with this?
Thanks!
Katie

=IF(Status@row = "RESOLVED", "Green", IF([DUE DATE]@row < TODAY(), "Red", IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green")))
Now I will explain a technique for writing long nested IF statements
You will need
1. Smartsheet (Works with Excel As Well)
2. Notepad or Notepad++.. A simple Text Editor/Scratchpad
Don't just jump in and start writing.. look at the logic cases
You said
Green = [Status] is either 1) "Resolved" or 2) [Status] is "Open" and [Due Date] is in the future
Yellow = [Status] is "Open" and [Due Date] is in 14 days or less (including today)
Red = [Status] is "Open" and [Due Date] is in the past
So if we started with writing for green it looks like we would have a lot of checks for AND Cases and OR Cases
"IF(AND(Status@row=OPEN,[DUE DATE]=..."
But if we walk through the logic and use our brains we can simplify it
IF#1. If it is resolved.. no matter what the date then it is GREEN
Then we can assume everything else is OPEN and not bother checking for it. Then the determining Factor becomes the DUE DATE and only the DUE DATE
IF#2. If the DATE is in the past then it is RED.. always
Then the next check becomes just for 14 days.. But not really..
Again If it is within 14 days then it is yellow.. If it is not yellow it must be green
Just going to spend a bit here..
See how the logic simplified and we don’t have to check for between today and 14 days because we checked for the lower limit in IF#2.. No ANDS or OR's required
And we also don’t have to have any statement to check for greater than 14 days as it is the only logic case left.
OK... So... Finally
IF#3. If the DATE is Less than (or equal to) 14 days then YELLOW.
Leaving only Green Left
So we took that large problem and broke it down into 3 if statements
Now let's write them
I create 3 columns for the IF Statements
Call them IF1, IF2 and IF3
In IF1 we will write our first if Statement
=IF(Status@row = "RESOLVED", "Green", "IF2")
Pretty Simple.. and you see how the "IF2" is simply saying.. well IF2 will deal with that..
Then in IF2 we look at the next case
=IF([DUE DATE]@row < TODAY(), "Red", "IF3")
Again Simple and for more, you need to look at the next IF statement
* Note that this will show a "RESOLVED" case in the past as RED.. but don’t worry.. remember IF1 catches that and it will never get here !!
IF 3 is simply..
=IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green") or
=IF([DUE DATE]@row <= TODAY(14), "Yellow", "Green") depending on how you want to write it
* Again note you will get a yellow from the above statement for resolved in the past and overdue.. but IF1 and IF2 have taken care of those
Now comes the fun part !!
Copy each of those statements into notepad
Step 1:
IF1: =IF(Status@row = "RESOLVED", "Green", "IF2")
IF2: =IF([DUE DATE]@row < TODAY(), "Red", "IF3")
IF3: =IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green")
Delete the equals on everything but IF1
Step 2
IF1: =IF(Status@row = "RESOLVED", "Green", "IF2")
IF2: IF([DUE DATE]@row < TODAY(), "Red", "IF3")
IF3: IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green")
Now Looking at IF1 replace where you see with IF2 with IF2
Step 3
IF1: =IF(Status@row = "RESOLVED", "Green", "IF2") becomes:
IF1: =IF(Status@row = "RESOLVED", "Green", IF([DUE DATE]@row < TODAY(), "Red", "IF3"))
Now we have to do the same for IF3
Step 4
IF1: =IF(Status@row = "RESOLVED", "Green", IF([DUE DATE]@row < TODAY(), "Red", "IF3")) becomes
IF1: =IF(Status@row = "RESOLVED", "Green", IF([DUE DATE]@row < TODAY(), "Red", IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green")))
That’s it now you have the big Nested If statement that should work the first time !!
Paste it in your ANDON Column (That’s what RYG is called in Lean Manufacturing) and it should work
And you are Done !!

=IF(Status@row = "Resolved", "green", IF(AND(Status@row = "Open", ([Due Date]@row  TODAY()) > 14), "green", IF(AND(Status@row = "Open", [Due Date]@row >= 0), "yellow", "red")))

Hi @Katie Marion ,
Try this:
=if(AND(Status@row="Open",[due date]@row <TODAY()),"Red",if(AND(Status@row="Open",[due date]@row<=TODAY(14)),"Yellow",if(OR(Status@row="Resolved",AND(Status@row="Open",[due date]@row>TODAY()),"Green","")))
Let me know if it works!
Best,
Heather

@Dennis Knipfer , I tried the formula and it's populating the green light appropriately, but the rows that should be red say #INVALID OPERATION; I don't have any rows meeting yellow criteria so can't confirm.
@HeatherD, that formula says #INCORRECT ARGUMENT SET

=IF(Status@row = "RESOLVED", "Green", IF([DUE DATE]@row < TODAY(), "Red", IF([DUE DATE]@row <= TODAY() + 14, "Yellow", "Green")))

@bcwilson.ca thank you so much for your detailed answer! The formula worked but I also really appreciate your explaining the logic and how to think differently to simplify the variables.
