if not sp_field[] is initial.

  if sp_field CA '*-/'.
     message 'Error' type 'E'.
  endif.
endif.

Hi always,

Check them:

IF P_DATA CA '*'.
  WRITE:/ 'Invalid'.
ENDIF.

Replace them:

REPLACE ALL OCCURRENCES OF '*' IN P_DATA WITH ''.

Hello,

And depending of the domain of the field used in the select-options the ABAP do a self validations (without need of code).

For example if you use a numeric type, only numbers will be accepted in the select-options.

Hi,

We can do validation like this.

----

SELECTION-SCREEN

----

SELECTION-SCREEN BEGIN OF BLOCK b WITH FRAME TITLE tit.

SELECT-OPTIONS: so_ebeln FOR v_ebeln OBLIGATORY.

SELECTION-SCREEN END OF BLOCK b.

----

AT SELECTION-SCREEN ON

----

AT SELECTION-SCREEN ON so_ebeln.

PERFORM validate_ebeln.

&----

*& Form validate_ebeln

&----

FORM validate_ebeln.

SELECT ebeln

FROM ekpo

INTO TABLE it_ebeln

WHERE ebeln IN so_ebeln.

IF sy-subrc NE 0.

MESSAGE e020(z50871msg) WITH text-014.

ENDIF.

ENDFORM.

Not only the "-/-".....for any value which is not valid, this code gives error message.

Here , I am doing the validation for EBELN. According to ur requirement you can change this code.
