Rollup field does not work when child item is created by Power Automate

Posted on by 603

Hi all,

 

I've a strange issue:

In my database table I've a rollup field that counts the number of child items.

When a child record is manual created, the rollup field work fine. It's count the number of child items.

 

But I create also child records automatically with a Power Automate flow. But when a child record is created by Power Automate, the rollup doesn't work. I can click on recalculate but that does not matter. 

When I open the by power automate created child record manually press save, the calculation works fine.

 

I don't know what's the reason is that this works not when I create the child record with Power Automate. 

 

Does anyone has an idea?

 

FYI: There are no business rules etc. enabled.

    Hi @dennisb88 ,

     

    By default, each column is updated hourly.

    You could  find the key message in these document.

    If you want use flow to update/refresh the roll up field, you could use the http action in flow to call the dataverse api to refresh it.
