Sales Orders Add Invoice popup window Through Acumatica API

Can someone share an example showing how to insert an Invoice using the action "Add Invoice" through the API.

I'm really out of clues, this code is what I have tried out already, but unsuccessfully (orginally posted by Serg Rogovtsev modified to fit AddInvoice popup parameters):

SO301000result = context.SO301000Submit(
    new Command[] 
    {                                                         
        new Value { Value = "SO", LinkedCommand = SO301000.OrderSummary.OrderType },
        new Value { Value = ordNum, LinkedCommand = SO301000.OrderSummary.OrderNbr },

        //popup window                                           
        new Value { Value = "OK", LinkedCommand = SO301000.AddInvoiceDetailsDocType.DialogAnswer, Commit = true },
        new Value { Value = "OK", LinkedCommand = SO301000..AddInvoiceDetails.DialogAnswer, Commit = true },
        new Value { Value = "Invoice", LinkedCommand = SO301000.AddInvoiceDetailsDocType.DocType },
        new Value { Value = "C0000155", LinkedCommand = SO301000.AddInvoiceDetailsDocType.RefNbr, Commit = true  },

        new Key { Value = "='CPU00004'", FieldName = SO301000.AddInvoiceDetails.InventoryID_, ObjectName = SO301000.AddInvoiceDetails.InventoryID.ObjectName },
        new Value { Value = "True", LinkedCommand = SO301000.AddInvoiceDetails.Selected, Commit = true },

        SO301000.Actions.Save
    }
);
