Duplicate Email Notifications

Hi, 

 

I have a flow which uses the action 'List files in folder', it then has a condition to check if the last modified date = today's date, if yes then add a row to a Power Bi dataset and then send an outlook email.

 

The problem I am having is each time the flow runs I get a email with all the files for today and not just the ones since the last flow ran.

 

I apologise if this is a really basic concept, but how can I set it up so I only receive emails about those files added since the last flow ran?

 

Thanks in advance

Re: Duplicate Email Notifications

 

@Stephen1606 You may be able to use the addhours() expression to alter your condition.  For instance, if your flow is recurring every hour or so you can use addhours() or utcnow() to see if the modified field is less than an hour old, therefore new.  So it will be like saying "check if Created >= utcnow()-1hr"  That's completely not how you write it, but well, I'm super new at this too.

Re: Duplicate Email Notifications

Hi @ Stephen1606,

 

Could you please share a screenshot of the configuration of your flow?

Where is the folder that you mentioned saved in? Is it saved in your Onedrive for business?

Do you want the flow to send an email with all the files' name that are added to folder since the last flow ran?

How frequency would you flow run to get the files in the folder and send the email

 

I would offer you a workaround, please refer to screenshot below to create the flow:

Note:

1.The flow would run with a frequency of two hours.you could modify the frequency as your needs.

2.The expression in the condition would filter all files that are added to folder since the last flow ran, the expression as below:

@greater(items('Apply_to_each')?['LastModified'], addHours(utcNow(), -2))

 

If modify the frequency of six hours, you should modify the expression as below:

@greater(items('Apply_to_each')?['LastModified'], addHours(utcNow(), -6))

 

You could refer to link below to learn more about the workflow definition language:

https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-workflow-definition-language

 

 3.The expression in the condition 2 would check whether there are files be added to folder since the last flow ran, and if there are files be added to folder since the last flow ran, the flow would send the email notification, the expression as below:

@not(equals(length(variables('All files name')), 0))

 

4.The expression in the compose would convert the files' name to string, the expression as below

string(variables('All files name'))

 

The flow would run successfully as screenshot below:
