See any std fun module in SE37

you will find lot of this statements

TRY.

go_cucb->get_configuration(

EXPORTING

is_instance_version = ls_instance_version

iv_with_db_instance = iv_with_db_instance

iv_head_request = lv_head_request

iv_ref_request = lv_ref_request

IMPORTING

es_cbase = ls_cfg_head

et_configuration = lt_cfg

eo_cbase_ref = eo_cbase_ref ).

MOVE-CORRESPONDING ls_cfg_head TO ibase-conf. "#EC ENHOK

LOOP AT lt_cfg REFERENCE INTO ls_inst_ref.

MOVE-CORRESPONDING ls_inst_ref->* TO ls_ibco_inst. "#EC ENHOK

APPEND ls_ibco_inst TO configuration.

ENDLOOP.

CATCH cx_cbase_error INTO lx_error.

PERFORM raise_exception

USING

lx_error

space.

ENDTRY.

Hi,

Exceptions are situations that occur while an ABAP program is being executed, in which normal continuation of the program does not make any sense.

Exceptions can be raised either implicitly in the ABAP runtime environment or explicitly in the ABAP program.

For example, division by zero leads to an exception in the ABAP runtime environment. It is possible to determine this situation through a query in the ABAP program and to trigger an exception there.

See the demo program DEMO_HANDLE_EXCEPTIONS in se38.

*--

EXAMPLE FOR RUNTIME ERROR--

*DATA : VALUE1 TYPE I.

*VALUE1 = 1 / 0. "----

>>>>>> IT MAKES RUN TIME ERROR.

*WRITE : VALUE1.

*--

EXAMPLE FOR HOW TO CATCH THE ARITHMETIC ERROR AT THE RUN TIME USING SUBRC--

*DATA : VALUE1 TYPE I.

*CATCH SYSTEM-EXCEPTIONS ARITHMETIC_ERRORS = 1.

*VALUE1 = 1 / 0.

*WRITE : VALUE1.

*ENDCATCH.

*IF SY-SUBRC = 1.

*WRITE : ' IT MAKES ERROR'.

*ELSE.

*WRITE : VALUE1.

*ENDIF.

in abap program we handle exceptions based on value returned by the system variable SY-SUBRC.

if SY-SUBRC = 0.

means execution completed sucessfull.

if SY-SUBRC = 1........n.

means execution compleated not sucessfully.

if sy-sbrc = 0.

write:/ 'execution sucessfull.

**here write logic as per u r requirement

else sy-subrc = '1'

message

elseif sy-subrc eq '2'

message

elseif sy-subrc eq '3'

message

elseif sy-subrc eq '4'

message

endif

Messages are defined in SE91..

These messages are of 5 types..

A Termination Message

The message appears in a dialog box, and the program terminates. When the user has confirmed the message, control returns to the next-highest area menu.

E Error Message

Depending on the program context, an error dialog appears or the program terminates.

I (Information)

The message appears in a dialog box. Once the user has confirmed the message, the program continues immediately after the MESSAGE statement.

S (Status Message)

The program continues normally after the MESSAGE statement, and the message is displayed in the status bar of the next screen.

W (Warning)

Depending on the program context, an error dialog appears or the program terminates.

X (Exit)

No message is displayed, and the program terminates with a short dump. Program terminations with a short dump normally only occur when a runtime error occurs. Message type X allows you to force a program termination. The short dump contains the message ID.
