Description

The functional method IS_PRODUCTION_SYSTEM of the class CL_ABAP_DEMO_SERVICES is called predicatively in a control statement IF to ensure that the current system is not a production system. The method called is a predicate method.

The functional method GET_SPFLI of the class CL_DEMO_SPFLI is then called predicatively once in a control statement IF and once in a conditional expression COND. In this case, it is not a predicate method. The relational expressions are true or false, depending on whether the internal table returned is empty or filled.
