Hi @mdevaney and @Anonymous
Thanks for your answers. I was testing all of your proposals and some others too. I'm still struggling to get a value entered at all into this SharePoint LookUp Columns or better said the dropdown representing this lookup column.
Maybe some additional information: I'm having an EditForm connected to a SharePoint List with DataCards connected to columns of this SharePoint List. When leaving the Dropdown as it's created by Power Apps, I can easily choose an entry of the Status List (which is source of the Lookup Column). But I can't set one of these entries in the Status List as a default value.
Here some data:
SharePoint List "Expenses" has multiple columns. One of these columns is a lookup column to the SharePoint List "Status", it is looking up the Title Column of "Status".
Now, when adding an entry to the "Expense" list, the dropdown representing the lookup Column for "Status" should automatically choose the "Title"-Value of the "Status"-List entry with value 1 in the ID-Column.
Is this feasible?
Thanks
