Validating select-options entries

Question

hi
i need to check whether all entries in SELECT-OPTIONS range are valid or not.
*my select-options field is s-pernr as below.
SELECT-OPTIONS: s_pernr  FOR pernr-pernr.
*all valid entries from PA0000 table will be selected into pernr_table.
SELECT DISTINCT pernr
        FROM pa0000
        INTO TABLE pernr_table
        WHERE pernr IN s_pernr.
now i have to check all invalid pernr's in s_pernr.
s_pernr contains: 1, 5, 6, 7, 8, 9, 10.
PA0000 contains: 1, 2, 5, 8, 10, 11, 13, 15...
then pernr_table = 1, 5, 8, 10 only.
that means pernr 6, 7, 9 in s_pernr were invalid.
How to fetch these values  as s_pernr is SELECT-OPTIONS field and it may have any combination of values.

Hi,
  As far as what i get from your question is, user put multiple values in the LOW field of the select-option and you have to
check all the values entered in the select-option-LOW field.
  If this is the case, you can loop at select-option as show :-
1) create an internal table of type
BEGIN OF ty_pernr ,
   sign(1)   TYPE c,
   option(2) TYPE c,
   low       TYPE pa0000-pernr,
   high      TYPE pa0000-pernr,
END   OF ty_pernr.
2) create workarea of type ty_pernr.
data wa_pernr type ty_pernr.
3) loop at the select-option.
loop at s_pernr into wa_pernr.
    SELECT single pernr
   FROM pa0000
    INTO TABLE pernr_table
    WHERE pernr eq wa_pernr-low.
  if sy-subrc ne 0.
     "give error message.
  endif.
endloop.
Hope this solves ur problem.
