Raising and catching exceptions...between try and entry....

[Former Member]

Hi Team,

I have created onc z exception class ..i have few doubts regarding raising exceptions ...

my code is like this..

PARAMETERS: myamount TYPE i.

DATA: mysavings TYPE i VALUE 5000,

plannedbalance TYPE i,

ex TYPE REF TO ZCX_DEMO_EXCEPTION_TEST,

mes TYPE string.

START-OF-SELECTION.

RAISE EXCEPTION TYPE ZCX_DEMO_EXCEPTION_TEST EXPORTING amnt = myamount

saving = mysavings.

TRY.

plannedbalance = mysavings - myamount.

IF plannedbalance < 0.

. ENDIF.

CATCH zCX_DEMO_EXCEPTION_TEST INTO ex.

mes = ex->get_text( ).

MESSAGE mes TYPE 'I'.

ENDTRY.

...........my doubt is why we cant abel to cach the exception ..even we i catched them in TRY and entry.....for above code system is giving warning message...

but if we keep raise and catch statement between try and entry ...then no issues....it is working fine.

Please calrify me..

Hi Ramky,

EXCEPTION can be handled using CATCH statement only when the EXCEPTION is raised between TRY .. ENDTRY. You already have no issues when doing that properly.

Hi ,

Can you write your warning message ?

Halo Yramki,

You should ideally raise the exception inside the Method of a class . Then you should catch this exception either in another method or report.

That means

plannedbalance = mysavings - myamount.

should be done inside the method of Class say Check_balance

IF plannedbalance < 0.

RAISE EXCEPTION TYPE ZCX_DEMO_EXCEPTION_TEST EXPORTING amnt = myamount

saving = mysavings.

endif.

Now catching this exception inthe report.

create object l_object of the class.
try.
l_object->check_balance( ).
catch  ZCX_DEMO_EXCEPTION_TEST into l_exception.
mes = ex->get_text( ).
MESSAGE mes TYPE 'I'.
endtry.

Hi Ramaky,

I am Posting a Example Program of Using Raising Statement This Will Give Brief Idea Of how to use Raise Statement And Try and Catch also.

CLASS ABC DEFINITION.

PUBLIC SECTION.

METHODS M1 IMPORTING X TYPE I

Y TYPE I

EXPORTING Z TYPE I

RAISING CX_SY_ZERODIVIDE.

ENDCLASS.

CLASS ABC IMPLEMENTATION.

METHOD M1.

Z = X / Y.

ENDMETHOD.

ENDCLASS.

START-OF-SELECTION.

DATA OB TYPE REF TO ABC.

CREATE OBJECT OB.

PARAMETERS: P_X TYPE I,

P_Y TYPE I.

DATA LV_R TYPE I.

TRY.

CALL METHOD OB->M1

EXPORTING

X = P_X

Y = P_Y

IMPORTING

Z = LV_R.

CATCH CX_SY_ZERODIVIDE.

WRITE:/ 'EXCEPTION RAISED:'.

ENDTRY.

WRITE:/ 'DIVISION IS...',LV_R.

WRITE:/ 'END OF PROGRAM.......'.

This Will Definitely HelpFul To you.

Whenever a exception is triggered, an exception object is created. This object would contain more information on the error condition. This exception can be caught and handled using the TRY .. CATCH.. ENDTRY block.
