For the filling: Preheat the oven to 375 degrees F. Coat a 9-inch pie dish with the softened butter. Set aside.
In a large mixing bowl, stir together the cranberry sauce, granulated sugar and flour. Add the apples to the cranberry mixture, tossing to coat, and pour the mixture into the prepared pie dish.
For the crumb topping: In the same mixing bowl, stir together the oats, flour, brown sugar, melted butter, pecans and cinnamon. Sprinkle the mixture over the apples in the dish.
Bake until golden brown, 35 to 40 minutes. Serve warm or at room temperature.
