Interface implementation

Behavior on not implemented interface methods

Define the effect on not implemented interface methods.

Add DEFAULT IGNORE to advise ABAP to handle the call to this method if not implemented as a call to an empty implementation.

INTERFACE account.
  METHODS new_method DEFAULT IGNORE.
ENDINTERFACE.

Add DEFAULT FAIL to advise ABAP to raise an exception CX_SY_DYN_CALL_ILLEGAL_METHOD if the not implemented method is called. This is the default behavior.

INTERFACE account.
  METHODS new_method DEFAULT FAIL.
ENDINTERFACE.
