Hi Nasarat,
if you look at carefully you definitions of tables
TYPES: BEGIN OF tbl,
rc_n TYPE c,
rec_n(2) TYPE n,
END OF tbl.
DATA: itab_org type tbl1 occurs 0 with header line,
itab_rc type tbl1.
your DATA statement referes ITAB_ORG to a Type tbl1 which does not  exist in your TYPES statement.
your DATA statement refers to ITAB_ORG is not a internal table but a WORK Area as you have declared it as ITAB_ORG type tbl1.
If you want to declare and internal table ITAB_ORG - decalre it as
Data:ITAB_Org type standard table of tbl.
and define a explicit work area
DATA: wa_org type tbl.
Never use Occurs 0 and Header line as it coccupies lots of memories and your programs may dump in future . So please avoid occurs 0 and header line and instead decalre an explicit WORK AREA.
Similary declaration for internal table ITAB_RC it should be
DATA: ITAB_RC type standard table of tbl,
          WA_RC type tbl.
then after these declarations when you do a SELECT statement it should be
SELECT rc_n rec_n into ITAB_ORG from<DB table>.
The fields as declared in types should be called in the same sequence as you have defined above OR use INTO CORRESPONDING-FIELDS OF ITAB_ORG.
Hope this reolves your query and was useful.
if yes please do reward suitably
Thanks
