Transformation in SAP BI 7.0 routine

Question

Hi together,
if got the following problem I don't understand.
I've got a transformation between 2 DSO's.
Some characteristics in the target-ods are filled with routines.
The code for one of the characteristics:
Global Part of the routine:
$$ begin of 2nd part global - insert your code only below this line  *
data:
      lt_konto_kontotyp type table of zifs_ktn_ktntyp,
      ls_konto_kontotyp type zifs_ktn_ktntyp,
select * from zifs_ktn_ktntyp into table lt_konto_kontotyp.
$$ end of 2nd part global - insert your code only before this line   *
Now I expected to use the filled table lt_konto_kontotyp in the routine implementation
with the code:
class lcl_transform implementation.
  method compute_zifcm013.
  IMPORTING
    request     type rsrequest
    datapackid  type rsdatapid
   EXPORTING
     RESULT type tys_TG_1-/BIC/ZIFCM013
    data:
      monitor_rec    type rsmonitor.
$$ begin of routine - insert your code only below this line        -
... "insert your code here
*--  fill table "MONITOR" with values of structure "MONITOR_REC"
*-   to make monitor entries
... "to cancel the update process
   raise exception type CX_RSROUT_ABORT.
... "to skip a record
   raise exception type CX_RSROUT_SKIP_RECORD.
... "to clear target fields
   raise exception type CX_RSROUT_SKIP_VAL.
read table lt_konto_kontotyp into  ls_konto_kontotyp
with key kontotyp = '03'.
     result = ls_konto_kontotyp-konto.
$$ end of routine - insert your code only before this line         -
  endmethod.            
My problem is lt_konto_kontotyp isn't filled with data, the select in the global
part is not achieved?
Is there an error in reasoning?
King regards
Lars

Hi,
Just move the select satement in the Start routine under Class implementation
and while populating the data in the field routine make a read on the internal table with the keyfield fetching.
Just populate the data into a worka area for the keyfield combination and then move the corresponding fiedls to the the RESULT
in the field routine
Start routine changes:
CLASS lcl_transform IMPLEMENTATION.
Method
SELECT statement here
ENDMETHOD
Field routine changes.
READ TABLE <your internal table> INTo <work area>
WITH KEY <your conditions based on key field>
RESULT = <work area>-<your field>
