In these three days, you will get a deep insight into the many features by which CDS Views surpass classical ABAP Dictionary views, and you will learn to leverage the full potential of CDS when defining your own views. Particular highlights will be the extended join possibilities, calculations on database level (including currency conversions), nested views, associations and path expressions, input parameters, and the possibility to link CDS views to authorization checks.
