Hi Suman,

You can catch the arithmetic exception by using exception class CX_SY_ARITHMETIC_ERROR as below

Sample code:

          data lv_ex_msg               type string.
          data lx_sy_error              type ref to CX_SY_ARITHMETIC_ERROR.

          try.

               "here goes your code

          catch CX_SY_ARITHMETIC_ERROR into lx_sy_error.

                           "  you can get exception text as below

                         lv_ex_msg = lx_sy_error->get_text( ).

                         or

                     " lv_ex_msg = lx_sy_error->get_longtext( ).
          endry.

Hope this helps you.

Regards,

Rama

Hi Suman,

No need to use exception tab of method in your case.

You are just catching the text of exception.

....

We use the exception tab of method when we need to return some exception raised in the method to other method.

Example:

let us say we have methods : method_1 with exception EX_1 & other method method_2 which calls the method_1 inside

method method_2.

          call method method_1
               exporting
                 a = lv_p

               exceptions
                    ex_1 = lx_1.

endmethod.

Hope this helps you.

Regards,

Rama
