Description

An interface IF_DEMO_AMDP_INTERFACE and an abstract superclass CL_DEMO_AMDP_SUPERCLASS implement the tag interface IF_AMDP_MARKER_HDB and contain the method GET_SCARR, which meets the prerequisites of an AMDP method.

The interface method is implemented once as an AMDP method and once as a regular method in the classes CL_DEMO_AMDP_IMPLEMENT_HDB and CL_DEMO_AMDP_IMPLEMENT_OPEN. In the same way, the method of the abstract superclass is redefined in the fixed subclasses CL_DEMO_AMDP_SUBCLASS_HDB and CL_DEMO_AMDP_SUBCLASS_OPEN.

This program demonstrates how objects are created using either the AMDP method or the regular method and called polymorphically, depending on the current database.
