Change in PowerApps variable cannot trigger MS Flow

Posted on by Community Power Pla... Microsoft Employee

Hi,

Please I need your help, I'm now creating a PowerApp and MS Flow,

I have an app like this, when "Save" button is clicked", will trigger "Set(HaveNewConv,true);SubmitForm(Form1)", then HaveNewConv will change to "true".

Then I have a flow trigger: "When an existing item is modified", if HaveNewConv=true, an email will be sent.

The problem is, even HaveNewConv is true, the flow is not triggered.

Hope anyone can help me with this or hopefully there is a way to be done. Thanks in advance.

Hi @Anonymous ,

The formula to trigger the flow from PowerApps should be:

If(HaveNewConv=true,FlowInApp.Run(xxx),false)

But in this flow, the trigger should be "Ask in PowerApps", not "When an existing item is modified".

More information about start a flow in app, please refer to:
https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/using-logic-flows
