How to check if a field (date) is blank AND it is within a specific number of days then send email

I have a business process where I need to take the following steps....just not sure how to code it in FLOW:

 

Step 1: Determine if [Funded End Date] is NOT blank

Step 2: IF [Funded End Date] field IS blank do nothing  

Step 3: IF NOT blank determine if [Funded End Date] is 1 day greater than today

Step 4: If YES send an e-mail to specific people | If NO do nothing

 

Run this everyday at a specific time

 

This seems to be a pretty standard problem and I've used this code @equals(formatDateTime(item()?['Funded_x0020_End_x0020_Date'], 'MM/dd/yyyy'), formatDateTime(addDays(utcNow(), 10), 'MM/dd/yyyy'))   before to send notices.

 

The issue I'm running into is that the not all the Funded End Date fields have data, and won't.  So I the first part of the code throws an error becuase it's trying to evaluate a blank field

Thanks in advance for any help! 🙂

I came across a similar issue today and couldn't find a solution in the community, but then found a workaround that may be of interest for some users for determining if a date field is blank:

 

Value(Today()) - Value('Due Date') = Value(Today()) returns True if Due Date is blank.

Hey DarenD,

 

I have ran into issues trying to evaluate too much in one expression condition - even if everything makes logical sense. Now I split up more steps, both Flow and my coworkers seem to like it better.

 

I would

  1. Initialize a boolean Variable outside the loop
  2. Then inside your Apply to each, Set the Variable something like
    1. Set boolean Variable = not(empty(item()?['Funded_x0020_End_x0020_Date']))
  3. Add another conditional branch where if the Fund date is TRUE (not empty) continue on to your other within 10 days condition, else do nothing

Capture.PNG

Sooo...what action/condition am I looking for to create the variable?  I can't seem to find it in the FLOW actions.

Oh my gosh....as soon as I posted this I found it. Sorry. 

Charles_John,

     I think I've followed the instructions provided but can't find the "true" boolean value. What am I missing?

 

VariableIssue.png

I basically do the same exact thing in my Flow. I first check if the date field on this SharePoint list is NOT blank with the following code inside a condition:

 

@not(empty(triggerBody()?['column name goes here']))

(the above is under an Apply to Each, just like you have it). So, if it is empty, nothing happens, if it is NOT empty, it goes to another condition where it checks if the date from the list is 30 days away from today or not. If it is not, nothing happens, if it IS 30 days away from today, I get an e-mail reminder sent to me.

 

@equals(formatDateTime(item()?['Nextauditdue'], 'MM/dd/yyyy'), formatDateTime(addDays(utcNow(), 30), 'MM/dd/yyyy'))

I must be missing something, because I've got a Definition Error (see arrow) and I can't find "true" in condition value.

 

VariableIssue2.png

Hey @DarenD

 

I actually use it without the variable initilization and true/false checking. I just add a condition under the Apply to each step and go to edit in advanced mode and paste the code in there. Also make sure the title of your column is correct but it looks like you've already done this from your screenshot.

Ah, let me try that and see if I can kick start this bad boy!

krisof805,

 The FLOW ran but I didn't get a notice and I've got one date set to 8/21/2018 (trying to test for just 1 day to see if I can get it to work).  Please see the two pix below:

 

Something Didn't workSomething Didn't workNot sure if code is incorrectNot sure if code is incorrect

@DarenD

 

I think your first screenshot indicates that the Flow didn't get to that step because the item was empty in that particular instance?

 

The second screenshot has your date out 10 days, and not 1, if I am not mistaken. I think you would need a date for 8/30/2018 or 8/31/2018 for the Flow to evaluate to true and send you an e-mail.

The not(empty(item()?['Funded_x0020_End_x0020_Date'])) needs to be an expression, or use the @ operator as I think you did in your next attempt

@DarenD

 

Using this approach you are referring to the wrong object.

@not(empty(triggerBody()?['RD_x0020_Funded_x0020_Expiration_x0020_Date'])) 

 

You want to referrence each element in the loop. Use below instead:

@not(empty(items('Apply_to_each')?['RD_x0020_Funded_x0020_Expiration_x0020_Date'])) 

 

Using the Expression and Dynamic Content tab to select your elements and build your formulas will help avoid the incorrect objects.

 

 

For your second box highlighting the comparision value in the condition, again, you can type in true in the Expression fx box. I think you can also directly just type in true to the comparision text box.

So I'm now a bit confused.  This is due to me being so new at FLOW but this is clearly an important issue for me to get fixed as I'll be using it in several other FLOWs.  

 

Charles_John,

    I added the code where you recommended, I believe, and it did run but no notice went out. I feel like I'm super close and just missing somethign small. You and Kristof805 are being super helpful and patient and I really, really appreciate it!!! 

 

So I have file in my library with an RD Funded Expiration Date of 8/22/2018, this is my test file.   

 

In my "Apply to Each" Action I have the first condition of:

 @not(empty(items('Apply_to_each')?['RD_x0020_Funded_x0020_Expiration_x0020_Date'])) 

 

If YES then second condition of:

 @equals(formatDateTime(item()?['RD_x0020_Funded_x0020_Expiration_x0020_Date'], 'MM/dd/yyyy'), formatDateTime(addDays(utcNow(), 1), 'MM/dd/yyyy'))

 

If RD Funded Expiration Date is 1 day ahead (YES) then send an e-mail.  What am I missing?

@DarenD

 

Your code looks good to me! Have you checked any of your runs for what is inside the Get files (properties only) -> Outputs -> Body results? That shows all the stuff your Flow is getting back from your files, you should see your dates there.

 

Have you tried a test run or two with this latest setup? Do you get a failure? Runs okay but no e-mails?

Hi DarenD,

Glad to help! Couple suggestions:

 

1. Add an action on the No/False branch of your condition to help in debuging. Then you'll be able to see if the condition isn't being evaluated as expected. This is why I also recomend Initializing/Setting variables. It's easier to see what's happening when debugging.

  • Note that your comparing sharepoint dates - which i'm assuming aren't entered in UTC time - against UTC now. I don't think this is the error in this case, but may cause timing differences in the future depending on what region you're in.

2. I would suggest building expressions using the Dynamic content selections and Expression formula until you're more familiar with objects. This will ensure you have correct references.

  • In your second condition is this giving you your expected value?
    •  @equals(formatDateTime(item()?['RD_x0020_Funded_x0020_Expiration_x0020_Date'], 'MM/dd/yyyy'), formatDateTime(addDays(utcNow(), 1), 'MM/dd/yyyy'))
  • I think it might, but you could change to 
    •  @equals(formatDateTime(items('Apply_to_each')?['RD_x0020_Funded_x0020_Expiration_x0020_Date'], 'MM/dd/yyyy'), formatDateTime(addDays(utcNow(), 1), 'MM/dd/yyyy'))

 

I just tried to make sure everything is working and it is with the following code and item with the date of 9/20/2018 (that's 30 days away from today according to Flow):

 

Expiration.png

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If the a date does end up being empty, the 30 days away step will throw and error saying that it did not get to that step but overall the Flow calls the run a success and so do I.

Charles_John,

    I added an e-mail in the first condition and recieved 200+ e-mails on items that had blank funding date fields. So that part works. However, the next condition isn't working properly. Even when I added your code updates.  See below:

email1.pngCodeIssue4.png

@DarenD I think that means that the Flow did not make it to that step (which is fine .. if a date is blank you can't compare it to a date from 30 days from now) but @Anonymous sounds like they know more than me. 

 

So the blank date part is working. Did you set any dates to 8/22/2018 so you would get a single e-mail if the Yes side of the condition evaluates?

Yes, I have 1 file with that date for testing purposes.  I think FLOW hates me! LOL!
