Loop Up Routine - Update Information Required

Question

Hello All,
I have a DSO1 with just one key field K1 in it.
I have another DSO2 with different structure and the K1 field of DSO1.
And i have a Source Cube.
I am loading data from Cube to DSO2 and i have to do a look up from DSO1 such that if the K1 of source cube is matching the K1 of DSO1 then the record should be loaded in DSO2 if the K1 of cube does not match that of DSO1 then that record should be ignored and next record should come and so on.
Please suggest me a Start routine so that it recognises the looK up DSO1 and its field K1 and also that the record from cube should not be repeated again and again.
Regards

Hi,
I am using the following code. Please correct me.
This does not work.
data : ls_znvchsv3 type _TY_s_sc_1,
           ls_znvchsv4 type _TY_s_sc_1,
           lt_znvchsv3 type _TY_t_sc_1,
           lt_znvchsv4 type _TY_t_sc_1,
           lt_znvchsv5 type _TY_t_sc_1,
           /bic/aznvchsv400 type _TY_S_sc_1.
    lt_znvchsv3 = SOURCE_PACKAGE.
    sort lt_znvchsv3 by /bic/zglome07.
    CLEAR: SOURCE_PACKAGE[].
LOOP AT lt_znvchsv3 INTO ls_znvchsv4.
Select * from /bic/aznvchsv400 into CORRESPONDING FIELDS OF
ls_znvchsv4 WHERE
/BIC/zglome07 EQ ls_znvchsv4-/bic/zglome07.
ENDSELECT.
APPEND ls_znvchsv4 TO lt_znvchsv5.
ENDLOOP.
    loop at lt_znvchsv3 into ls_znvchsv3
         where /bic/zglome07 = ls_znvchsv4-/bic/zglome07.
        append ls_znvchsv3 to lt_znvchsv4.
    endloop.
APPEND LINES OF lt_znvchsv4 TO SOURCE_PACKAGE.
