I have a product library which contains choice menu column. The name of the column is New Product?. And the choices are TRUE and FALSE.
I want to create a custom view which only shows Old Products. I'm able to create the view by filtering but I need additional setting. Let say if I create a new product today and the product becomes old product after 15 days. So the product automatically can be viewed in the Old Product view. I'm unable to create filter with date format.
I'm prohibited to use designer or any back end queries. Please assist.
