Hi everyone!

I do not know if I am in the right place, but I need help with writing a command in Power FX to trigger a custom button in our model-driven app in PowerApps. I searched the internet but could not find the right solution.

Scenario:

I have created a custom button in the model-driven app on the table 'Opportunity Line'. I need this button to update a toggle on the parent Opportunity when a user uses this button (set it to true). As a result, a cloud flow will be triggered.

Currently, I am using this command, but when I click the button, nothing happens:

Patch(

    Opportunities, // Parent entity name

    LookUp(

        Opportunities,

        Opportunity = ThisRecord.Opportunity // Match the OpportunityID in the child record with the parent

),

        'Convert to Sample Request': true

)

I know I am doing something wrong but I don't know what, as I am very new to Power FX commands.

Thank you!

Hi Partner,

Do you have to use Power FX command for this purpose?
Maybe consider using a workflow or javscript?

About Power Fx patch function, you can refer to the following documentation:

Hi,

This Fx formula will not work on your scenario as it get confused to which opportunity he wants to update. Use the below Power fx formula which will update the toggle field on the parent opportunity.

Patch(Opportunities, Self.Selected.Item.Opportunity,{Forecast:'Forecast (Opportunities)'.Yes})

In this formula Forecast is my toggle field in the Parent Opportunity which gets updated to ‘Yes’ when clicked on the button present in the Opportunity line.
