Limitation of using select-options or ranges

Question

Hi
I have the following code to fill the select-option AUFNR with the orders from SEL_TAB table, which I have to submit to another report to get a result set.
LOOP AT SEL_TAB.
   MOVE: 'I'   TO AUFNR-SIGN,
         'EQ'  TO AUFNR-OPTION,
         SEL_TAB-AUFNR TO AUFNR-LOW.
  APPEND AUFNR.
ENDLOOP.
I know that we can use the RANGES option also for the above scenario since I don't display the select-option AUFNR in my selection screen.
My question is, is there any limitation to how many number of values the RANGES or SELECT-OPTIONS can hold? Is it 200 or 256? I am not sure of this figure, can anyone give the exact number?
Thanks,
Bala.

Hi Bala,
  there's not SAP limitations for range dimension but there is a limitation about native SQL statement size.
In fact an open SQL statement (in ABAP language) will be translated in native SQL .
For example:
select * from mara where matnr in r_mara
will be translated in
SELECT ... FROM MARA WHERE MATNR = value1 OR MATNR = value2 etc...
So if your range is too large, the native SQL will exceed the maximum length (and short dump will occur).
with the following simple trick you can bypass the problem:
describe table rng_ebeln_marc lines i.
if i > 0.
  if i <= max_rng_rows.   "MAX NUMBER OF RANGE LINES
    select *
      from ekbe
      into table tekbe
     where ebeln in rng_ebeln_marc.
  else.
    from_i = 1.
    to_i = max_rng_rows.
    clear new_ebeln_marc.
    do.
      if i < from_i.
        exit.
      endif.
      append lines of rng_matnr_mara from from_i to to_i to new_ebeln_marc.
      select *
        from ekbe
   appending table tekbe
       where ebeln in new_ebeln_marc.
       clear: new_ebeln_marc, new_ebeln_marc[].
       from_i = from_i + max_rng_rows.
      to_i = to_i + max_rng_rows.
    enddo.
  endif.
  sort tekbe by ebeln ebelp zekkn vgabe gjahr belnr buzei.
endif.
This will split the sql statement into more (and shorter) statements. The result will be joined.
Let me know if you need further infos.
