you can write simple like as below

all printable sign's which are used in Web

DATA: vergleich_string(100) VALUE

'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.

parameters p_vbeln like vbap-vbeln.

at selection-screen on p_vbeln.

CONCATENATE vergleich_string ',./!@#$%&*-_+=~|\[{]}()"'

INTO vergleich_string.

if p_vbeln ca vergleich_string.

give error message.

endif.

Thanks

Send the parameter to NUMERIC_CHECK function module and see the return type. If it is not NUMC, issue error. See below.


DATA: htype LIKE dd01v-datatype.

PARAMETERS: p_order LIKE likp-vbeln.

AT SELECTION-SCREEN.

  CALL FUNCTION 'NUMERIC_CHECK'
    EXPORTING
      string_in  = p_order
    IMPORTING
      string_out = p_order
      htype      = htype.
  IF htype <> 'NUMC'.
    MESSAGE e162(00) WITH 'Enter numeric value'.
  ENDIF.
