Error while writing a rotuine!! Help me

Question

Hi Guys,
Bleow is the code :
"DATA: L_S_DATAPAK_LINE TYPE TRANSFER_STRUCTURE.
LOOP AT DATAPAK INTO L_S_DATAPAK_LINE.
IF L_S_DATAPAK_LINE-ITM_SC_H_OBJ_ID = '0010092184'.
   L_S_DATAPAK_LINE-ITM_DESCRIPTION  = 'PT/UIOPLANTRONICS U1OP'.
   modify DATAPAK from L_S_DATAPAK_LINE.
ELSE L_S_DATAPAK_LINE-ITM_SC_H_OBJ_ID = '0010115691'.
     L_S_DATAPAK_LINE-ITM_DESCRIPTION  = 'banner 2008 year planner'.
modify DATAPAK from L_S_DATAPAK_LINE.
ENDIF.
CLEAR L_S_DATAPAK_LINE.
ENDLOOP."
When i am checking this code its throwing an error as :E:Unable to interpret "L_S_DATAPAK_LINE-ITM_SC_H_OBJ_ID". Possible causes of error: Incorrect spelling or comma error.
Guys pls let me know wer i am doing mistake? its bit urgent.
Points assured.

I know you didn't ask this, but I would change my loop to:
LOOP AT DATAPAK INTO L_S_DATAPAK_LINE.
      WHERE
             ITM_SC_H_OBJ_ID = '0010092184'     OR
             ITM_SC_H_OBJ_ID = '0010115691'.
  If L_S_DATAPAK_LINE-ITM_SC_H_OBJ_ID = '0010092184'.
         L_S_DATAPAK_LINE-ITM_DESCRIPTION = 'PT/UIOPLANTRONICS U1OP'.
  else.
         L_S_DATAPAK_LINE-ITM_DESCRIPTION = 'banner 2008 year planner'.
  endif.
  MODIFY  .....
  ENDLOOP.
Using this method will increase performance if you are going through a large number of records because you only process the code if the Object ID's are one of the two selected.  Also, in your code, you missed a second "IF" after your else statement.  Your code assumes only two options where my code guarantees only two options exist.
I must be bored today!  And, I'm not really an ABAP'er, I just play around with it a bit, so I might have missed something obvious.
Good Luck!
