Show Text when No Data in a Table

Hi Juan

I am glad that it is finally working!

This code should work for you:

let
    Quelle = SharePoint.Tables("https://axa365.sharepoint.com/sites/AXA-MicrosoftTeamsService", [Implementation="2.0", ViewMode="All"]),
    #"5aaa8718-9d99-4675-9214-078e6e3131a7" = Quelle{[Id="5aaa8718-9d99-4675-9214-078e6e3131a7"]}[Items],
    #"Hinzugefügte benutzerdefinierte Spalte" = Table.AddColumn(#"5aaa8718-9d99-4675-9214-078e6e3131a7", "Custom_Summary_as_Text", each Html.Table([Summary],{{"PlainText",":root"}})),
    #"Erweiterte Custom_Summary_as_Text" = Table.ExpandTableColumn(#"Hinzugefügte benutzerdefinierte Spalte", "Custom_Summary_as_Text", {"PlainText"}, {"Custom_Summary_as_Text.PlainText"}),
    Custom1 = if Table.IsEmpty(#"Erweiterte Custom_Summary_as_Text") then Table.InsertRows(#"Erweiterte Custom_Summary_as_Text",0,{ [#"Tracking-Number" = "Table Is Empty",#"Escalated" = "False"]}) else #"Erweiterte Custom_Summary_as_Text"
in
    Custom1

Let me know if it does.

Regards

Hugh
