ABAP code example for Function Module CNET_LOGIC_NETWORK





The ABAP code below is a full code listing to execute function module CNET_LOGIC_NETWORK including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).
