Customize library form by Data from Lists.

[Staba91]

Hello!

I have a SharePoint Library to customize form with PowerApps. Some Data are retrieved from Lists. Unfortunately, when I save the app, Data are not recorded in Library row.

Please HELP!!!

@Staba91 Can you share more details about your app customizations?

1. How are you fetching list data and using it in library forms?
2. How are you saving data to library from customized forms?
3. What type of columns you are updating in library?

How are you fetching list data and using it in library forms?
==> The target columns are of LookUp type which retrieve data from lists.
Items = 'ListName'

How are you saving data to library from customized forms?
==> Using the SharePointIntegration:
DataSource = [@LibrayName]
OnSave = Set(
SharePointFormMode,
"SubmitForm"
);
SubmitForm(SharePointForm1);
Navigate(
SharePointForm1,
ScreenTransition.None
)

What type of columns you are updating in library?
LookUp type columns

Best regards

It's resolved. On Items fiels of each DataCardValue:
Items = Choices([@LibraryName].ListName)
