Urgent : Doubt in writing a code in start routine

Question

Hi all ,
             I am BI 7.0 system , I have doubt in writing a code in start routine .
1) i have to extract the data first from a custom table based on one condition and then placing it into internal table .
2) Now i have to loop at source_package for a particular region field say "ASIA". with this result i have to check for the correponding entries in custoom table .
   if condition is not true (i.e ) with entries or not matching then delete that particular record from source_package.
i have written a small logic for this . but this is producing any ouput , Please check it and also let me know for modifications .
thanks in advance.
select * from zcsp
    into corresponding fields of TABLE itab_T
    where
    ZBUSINESSUNIT = 'BC'.
loop at SOURCE_PACKAGE into ls_SOURCE_PACKAGE where /BIC/DPREGION = 'XE'.
             loop at itab_t into itab_w where zcategory =
               ls_source_package-/BIC/DPMAT/BIC/DPCAT.
                   if sy-subrc ne 0.
                     delete SOURCE_PACKAGE.
                   endif.
           endloop.
       endloop.

You're deleting the entire input package.  You only want to delete the one row.
DATA: g_tabix TYPE sy-tabix.
SELECT * FROM zscp
INTO CORRESPONDING FIELDS OF TABLE itab_t
WHERE zbusinessunit = 'BC'.
SORT itab_t BY zcategory.
LOOP AT source_package INTO ls_source_package WHERE /bic/dpregion = 'XE'.
  g_tabix = sy-tabix.
  READ TABLE itab_t WITH KEY zcategory = ls_source_package-/bic/dpmat/bic/dpcat TRANSPORTING NO FIELDS BINARY SEARCH.
  IF sy-subrc NE 0.
    DELETE source_package INDEX g_tabix.
  ENDIF.
ENDLOOP.
