Dear Abappers,

I am facing some issue . I have written this code.

try.

    MODIFY dt_tabcst INDEX 0.

CATCH cx_root.

   EXIT.

ENDTRY.

but unable to catch the exception.  I  get screen dump  .  table_invalid_index    runtime error.  How  can i catch this error.?

Regards

index 0 is invalid. must be at least 1

you need to declare one variable to catch exception.

Please follow following snap of code to catch the exception.

data : res type i.
parameters : num1 type i,
             num2 type i.

data : obj type ref to cx_root.
data : msg type string.
try.
  res = num1 / num2.
  write 😕 'result =', res.
  catch cx_root into obj.
    msg = obj->get_longtext( ).
    write 😕 msg.
  endtry.

suppose we are dividing two number. by mistake i divided nmber by 0.

that time it will work.

Index should not be zero. Please check. Hope the modify statement written inside the loop and Table dt_tabcst is defined with header line.

Just put break point on Modify statement and check system variables SY-MSGID / SY-MSGNO to get the details of error.

Hi Aneel,

TABLE_INVALID_INDEX is uncatchable runtime error.

To verify that an exception is catchable, go to ST22 and see column Exception.

If exception is filled is catchable, if not is uncatchable.

Angelo.

THANKS Angelo,

I got it.

ST22   is also useful.
