Extracting an Exception Variable from a RAISE Statement

You can add a variable declaration for an exception to the method signature as well as to source code in order to instantiate the exception before raising it. This enables you to handle the result of the exception, for example, to display it in a message.

Prerequisites

This functionality is provided since SAP NetWeaver 7.4 SP05 / SAP NetWeaver 7.3 EHP1 SP11 and higher.

Context

Example

To copy the source code example, click here Code Example Before Execution
In the implementation of the `drive` method, an exception with the `cx_error` type is raised when the `i_speed` variable is less than zero.	In the signature of the `drive` method, the `exc` exception variable is added with `TYPE REF TO` of the selected exception class. In addition, this exception variable is added in a `CREATE` statement and called in a `RAISE` statement. The former `RAISE EXCEPTION TYPE` statement is deleted. You can now reuse or process the value of the exception variable in order to handle this case of an exception.
