How to 'inner join' internal table or cluster table ??

Question

Hi,
when i inner join table BSEG it said is a cluster table can't be inner joined .
i wonder how i can "inner join" bseg with a internal table such as
data: begin of i_bseg_trans,
        bukrs like bseg-bukrs,
        gjahr like bseg-gjahr,
        belnr like bseg-belnr,
        total_runtimes like i_runtimes-total,
        already_runtimes like i_runtimes-already,
        left_runtimes like i_runtimes-left,
      end of i_bseg_trans.
and similar things trouble me  when considering several internal tables .
thanks for any help!!

Answer 1

Hi,
but if there's more than 2 tables,  for example
data: begin of it_bseg occurs 0,
        bukrs like bseg-bukrs,
        else_1 type i,
     end of it_bseg.
data: begin of t occurs 0,
        bukrs like bseg-bukrs,
      end of t.
data: begin of r occurs 0,
        bukrs like bseg-bukrs,
        else type c,
      end of r.
select bukrs from bkdf into table t.
select bukrs from bkdf into corresponding fields of table it_bseg.
select bseg~bukrs      "else_1
from bseg      "it_bseg
  into table r
  for all entries in t
  where bseg~bukrs = t-bukrs.
      " and it_bseg-bukrs = t-bukrs.
in the select clause i mean whether there's a method similar to the way just drop the " in my code.
now my solution is to use another loop on it_bseg, but i think when table amount is large this is really a boring solution.
