30days notification for multiple people - Library properties Not a list

(0) ShareShare
ReportReport
Posted on by 633

Hello all, 

 

Could you please do me a favor?

This is a library's Property.  Not a list. 

Multiple people should be designated as secondary Document Owners. They will receive a reminder email 30 days before the next review date. But the workflow didn't work. It worked in the list. 

 

Thank you. 

 

The below is a library property in Sharepoint.

    @happyyear You are using Key Value mode in the Select action—you need to be using Map mode. As per my instructions above:

     

    Click on this icon to switch from Key value to Map Mode.

    Insert the email dynamic content from the multi-person column into the Map field. Important: Once you do this, the select action will automatically nest itself inside an Apply to Each action. This action isn't necessary. Pull the Select action outside of the Apply to Each action and delete it (the Apply to Each action).

    @happyyear Can you show what dynamic content you have in your Select action?

    @creativeopinion Thank you for your help. I spent many hours to resolve this issue. 

    The main issue is that, your flow is below

    happyyear_0-1705952154528.png

    I exactly followed your instruction but my output is 

    {"123happy@gmail.com":""};{"1234happy@gmail.com":""};{"12345happy@gmail.com":""}

     

    I don't know where the ":" is coming from. 

     

    Mine is a library. Not a list. probably that is why.

    @happyyear If the Secondary Document Owners is a multi-person column, the Search for Users (V2) action isn't required. You should be able to pull the email addresses from that column.

     

    Use a Select action instead to get the values from the mulit-person column.

    Add a Select action. Insert the dynamic content of your multi-person column into the From field. In my case, it's Assigned To.

     

    Click on this icon to switch from Key value to Map Mode.

    Insert the email dynamic content from the multi-person column into the Map field. Important: Once you do this, the select action will automatically nest itself inside an Apply to Each action. This action isn't necessary. Pull the Select action outside of the Apply to Each action and delete it (the Apply to Each action).

    Run a test. The Select action will return an array of email addresses. To use these addresses in a Send an Email action you need to convert the array into a string.

    Add a Join action. In the From field, insert the output from the Select action above. Email addresses need to be separated by a semi-colon. Insert a semi-colon into the Join with field.

    Run a test. The Join action will output a string of email addresses separated by a semi-colon.

    In your Send an Email (V2) action insert the output of the Join action into the recipient field. However, I would suggest you use your own email address for testing purposes. You can insert the output of the Join action into the body of the email instead.

     

    This way you can verify who the email will be sent to. Ensure the flow is running as expected before you replace your email address in the recipient field with the actual recipient(s) email address(es)
