ABAP Objects in Release 7.40

1 Parameter interface of functional methods
2 Interfaces in Test Classes
3 Exception handling


ABAP_MODIFICATION_1 Parameter Interface of Functional Methods

Alongside the return value defined using RETURNING , a functional method can now have any number of other formal parameters . Previously, only input parameters were possible.
Accordingly, functional method calls can now be used with the additions EXPORTING ,
IMPORTING , and CHANGING , so that actual parameters can be bound to the additional formal parameters.
When the input parameters of a method are declared, the addition PREFERRED PARAMETER can now also be specified, if the method has output parameters or input/output parameters. The only requirement is that all input parameters and input/output parameters are optional.


ABAP_MODIFICATION_2 Interfaces in Test Classes

In test classes, you can specify the new addition PARTIALLY IMPLEMENTED in the statement INTERFACES , which allows you to only partially implement interfaces. This is particularly useful in test doubles.


ABAP_MODIFICATION_3 Exception Handling

If a class is specified dynamically after TYPE in the statement
CREATE OBJECT and the class does not match the static type of the reference variable, the exception can now be handled using the exception class
CX_SY_CREATE_OBJECT_ERROR .
