Hi,

dump would occur if you dont catch all the exceptions.

Cheers,

Hi Ricardo,

The concept of Try and Catch is when ever any exception comesup and you want to handle by your program then you need to use the Try and Catch Statement.

Check out the following code

It catched devide by zero error.


DATA: w_var TYPE i,
      text   TYPE string,
      oref   TYPE REF TO cx_root.

TRY.
    w_var = 10 / 0.
  CATCH cx_sy_arithmetic_error INTO oref.
    text = oref->get_text( ).
  CATCH cx_root INTO oref.
    text = oref->get_text( ).
ENDTRY.

WRITE / text.

TRY and END TRY is used with the CATCH statement. These statements used to handle the Exceptions at the Runtime so the program will not go into the Dump.

What ever code we wrirter inside the Try ENDTRY block is handled for Exception.

Class CX_ROOT is the superclass for global exceptions. If you catch this, you should catch most exceptions; however the error messages you get may not be as helpful as those you would get from one of the more specific class based exceptions.
