Merging 2 ODS into 1 Cube

Question

Hello,
i have 2 ODS-Objects (ODS_A & ODS_B) and have to merge the content into a Cube by an update-routine. The problem is, that it is not a 1:1 merge.
Here is a short description of the merge-logic.
In the update-routine i declared 2 internal tables and "move" the content of the ods-object to the tables (see source-code). after that i want to join the 2 internal tables, but it looks like it is not possible. i know that oracle is able to do it in the following way.
select * from ods_content_a as a, (select col1, col2 from ods_content_b group by col1) as b where a-col1 = b-col1.
knows anyone a solution to join 2 internal tables or to reproduce the oracle sql-statement???
data: ods_content_a like ods_a
data: ods_content_b like ods_b
select * into ods_content_a from ods_a
select col1 sum( col2 ) into ods_content_b from ods_content_b group by col1
select col1, col2 from ods_content_a as aods_content_b as b where a-col1 = b-col2.

Answer 1

i know how i have to join 2 tables in abap... the question was how i can join 2 internal tables or reproduce the already mentioned oracle statement.
DATA: ods_a type standard table of /BIC/AODS_A.
DATA: ods_b type standard table of /BIC/AODS_B.
DATA: BEGIN OF wa,
        col1 TYPE i,
        col2 TYPE p decimals 2,
      END OF wa.
DATA: itab LIKE SORTED TABLE OF wa WITH NON-UNIQUE KEY col1.
select * into table ods_a from /BIC/AODS_A.
select col1 sum( col2 ) as col2
  into corresponding fields of table ods_b
  from /BIC/AODS_B group by col1.
select a~col1 a~col2 into table itab
  from ods_a as a inner join ods_b as b
  on a~col1 = b~col1.
At the last select statement i get following error-msg.
E:"ods_a" is not defined in the ABAP Dictionary as a table, projection view, or database view.
