ABAP RAISE EXCEPTION Statement syntax, information and example SAP source code

RAISE

Short Reference

ABAP Syntax_1 RAISE exception.

What does it do? This statement raises the
non class-based exception exception .
RAISE can be specified in a method only if the non-class-based exception is defined in the interface of the method.
Specify RAISE in function modules only if the non-class-based exception is defined in the interface of the function module.
It is possible to specify RAISE in all other positions, but we advise against it.
After the exception exception is raised, the system proceeds as follows:
If the exception is raised in a method or function module whose caller assigns a return value to the exception, then the procedure ends immediately, the system returns to the calling position, and the system field sy-subrc is set according to the assignment.
If the exception is raised in a method or function module whose caller does not assign a return value to the exception, a runtime error is then triggered whose short dump contains the name of the exception.
If the exception is raised in a subroutine, the system searches for the first function module in the procedures of the preceding call stack. If it finds a function module of this type and the exception is defined in it, the system acts as though the exception was raised in this function module. Otherwise, a runtime error occurs.
In all other processing blocks, raising a non class-based exception produces a runtime error that immediately ends the program.
This form of the statement RAISE cannot be used in the same processing block as the statement RAISE EXCEPTION or the addition
THROW in a conditional expression to raise class-based exceptions.

Latest notes: The statement MESSAGE with the addition RAISING also raises a non class-based exception. In cases in which non-class-based exceptions are still used, this statement is preferred instead of RAISE , because it offers the option of adding a text to the exception.
If a procedure is exited by raising an exception, the content of the formal parameter for which the pass by value is defined is not assigned to the respective actual parameters.
