Patch(SPlist, SelectedItem, Form_1.Updates, Form2.Updates,Form3.Updates);
)

Hi @Ashok2 ,

The Errors function needs to be used after the patch - you need to check on the result of the Patch after it has been applied.

Hi @Ashok2 ,

Currently, within PowerApps app, the Form validation mechanism only work when you use SubmitForm function to submit form data, it would not work for Patch function.

In addition, based on the formula that you mentioned, I think there is something wrong with it. Please consider modify your formula as below:

If(
    IsEmpty(
            Errors(
                    SPlist,  // Modify here. Specify your SP List data source here
                    Patch(SPlist, SelectedItem, Form_1.Updates, Form2.Updates, Form3.Updates)
            )
    ),
    ResetForm(Form_1);ResetForm(Form2);ResetForm(Form3);Back(),
    Notify("There is something wrong when you submit form data" & First(Errors(SPlist)).Message, NotificationType.Error)
)

Please take a try with above solution, check if the issue is solved.

Hi @Ashok2 ,

Please note that the Submitform will work exactly like a patch, but if there are not changes to update, it won't send any data to the server which is quite cool.

Below is a method that we are using for form validation that is very easy to implement and works very well.

Let me know if you don't come right.
