Trying to add a new row to a "Shared Data Extension" using SSJS

Question

I'm trying to add a new row to a Shared Data Extension using SSJS. When I try to run my code I got this error:

"There was an error Adding the row(s)."

In another environment of Marketing cloud, the code works and does not give errors. Why is there an error?

My code:

<script runat="server">
    Platform.Load("core", "1");

    try {
        var de = DataExtension.Init("EXTERNAL KEY");
        var data = {
            status: "status",
            errorMsg: "errorMsg"
        }
       Write(de.Rows.Add(data));
    }catch(error) {
        Write(Stringify(error));
    }
</script>

Answer 1

Since you are running into the child BU but in Share data extensions.

Please you use "ENT." as prefix. Also instead of External Name Try using Data external Key.

Like this - DataExtension.Init("ENT.Data External Key");

Answer 2

To expand on the WHY. Shared data extensions are owned by the enterprise regardless of what BU made them.
