Creating a Non class-based exception

Non class-based exception can be used in functions and methods. Below I will show you how.

A. Creating a non class-based in a function.

Enter your variable in the exception parameter of your function in se37. Make sure to unmark the exception classes check box. 

Then, inside your function, you can trigger the exception by raising it. The syntax is shown below:

IF sy-subrc <> 0.

  RAISE ex_error.

ENDIF.

The calling program that calls the function should capture the exception as shown below:

      CALL FUNCTION 'Z_CUSTOMER_INFO'
        EXPORTING
          kunnr       = wa_main-kunnr
          bukrs       = wa_main-bukrs
        IMPORTING
          address1    = address1
          address2    = address2
        EXCEPTION

          ex_error    = 1.

IF sy-subrc = 1. "exception value will bee assigned to sy-subrc

    MESSAGE 'ERROR OCCURRED'TYPE 'E' DISPLAY LIKE 'I'.

ENDIF.
