End Routine is NOT modifying the DSO with new data after load into that DSO

Question

Hi all,
  I am creating an End Routine for DSO to populate a field ZFCMP_FLG (to store 'Y' ) with lookup from another DSO ZMDS_D01. This new field shows blank instead of 'Y', after activating the DSO. The RESULT_PACKAGE record is populated with 'Y' for ZFCMP_FLG  while debugging that End Routine and why it is NOT writing the modified records into DSO, please ? It is a Characteristic InfoObject with length 1 to store 'Y'. The following is some part of the code:
DATA: wa_fcmp_flag   TYPE c VALUE 'Y'.
LOOP AT RESULT_PACKAGE ASSIGNING <RESULT_FIELDS>.
    READ TABLE it_zmds_d01 INTO wa_zmds_d01 WITH KEY
                /BIC/ZAUFNR    = <RESULT_FIELDS>-CS_ORDER
                NOTIFICATN     = <RESULT_FIELDS>-NOTIFICATN  BINARY SEARCH.
     IF sy-subrc = 0.
       <RESULT_FIELDS>-/BIC/ZFCMP_FLG = wa_fcmp_flg.
    ENDIF.
ENDLOOP.
Thanks,
Venkat.

hi...
Since you are using Field symbol to loop the internal Table there is no need to use the MODIFY Statement in the loop.
So your code is correct only.
But here you have to check the status of READ TABLE command in the debug mode.
it may be failing that's why the RESULT_PACKAGE is not getting modified.
Plz check it.
Note: You may need to SORT the Int Table since you are using BINARY SEARCH. check below.
DATA: wa_fcmp_flag   TYPE c VALUE 'Y'.
Sort it_zmds_d01 by  /BIC/ZAUFNR    NOTIFICATN  .
LOOP AT RESULT_PACKAGE ASSIGNING <RESULT_FIELDS>.
    READ TABLE it_zmds_d01 INTO wa_zmds_d01 WITH KEY
                /BIC/ZAUFNR    = <RESULT_FIELDS>-CS_ORDER
                NOTIFICATN     = <RESULT_FIELDS>-NOTIFICATN  BINARY SEARCH.
     IF sy-subrc = 0.
       <RESULT_FIELDS>-/BIC/ZFCMP_FLG = wa_fcmp_flg.
    ENDIF.
ENDLOOP.
