Populating Many to Many Table with Power Automate

(1) ShareShare
ReportReport
Posted on by 22

Hello Everyone,

 

I am trying to design a flow to populate the connecting table that Dataverse creates when you make a N:N relationship.

I am using property address from the Contacts table and property address from the Property table to link them up.

 

How do I do this? I've done a flow that does a 1:N and that seemed simple enough, but this added complexity is making me stuck. 

 

For reference this was the flow I had for 1:N and it worked great:

    Hi, unfortunately you can't use the connecting table created by dataverse. 
    You’ll need to create your own custom table to serve as the connecting table.

    So going forward, should I even bother using the built in feature for Many to Many?

    Hello!

     

    You need to use the related row action in Dataverse to relate. Here is a M:M example of relationship between system user and role

    Hi @areseia 

     

    You can use the related action to add elements to N:N relationships

     

    The first thing you should do is filter the lists based on your need and then use the related action to add the elements from one table to the other

    You must create two table relation actions because you are looking to establish the N:N relationship
