Downloading Entire Table to MS Access

Question

Dear Gurus,
We are trying to download an entire table to MS Access. We have configured the RFC destinations and sucessfully downloaded the structures. However, When we try to use the FM TABLE_EXPORT_TO_MSACCESS, We got a dump. We have been trying hard on this with no resolution.  Its 12:35 AM now.
The code snippet and the dump are as follows. We use SELECT .. ENDSELECT ( with no success and CURSORS.
OPEN CURSOR WITH HOLD CURS  FOR
SELECT *
FROM MARA
DO.
FETCH NEXT CURSOR CURS
INTO TABLE I_MARA package size 20000.
REFRESH T_MARA[].
T_MARA[] = I_MARA[].
PERFORM DOWNLOAD_ACCESS.
IF SY-SUBRC <> 0.
EXIT.
ENDIF.
ENDDO.
CLOSE CURSOR CURS.
ENDIF.
FORM DOWNLOAD_ACCESS.
CALL FUNCTION 'TABLE_EXPORT_TO_MSACCESS'
  EXPORTING
    dbname                 = ws_c_filepath
    LANGU                  = SY-LANGU
    dest                   = dest
    tabname                = MARA'
    FLG_APPEND             = 'X'
    FLG_POPUP              = ''
tables
    dtab                   = T_MRA
EXCEPTIONS
   WRONG_FORMAT           = 1
   STRUCT_TOOLONG         = 2
   UNKNOWN_DATATYPE       = 3
   SYSTEM_FAILURE         = 4
   COMM_FAILURE           = 5
   OTHERS                 = 6
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
The dumo in this case was
Error in ABAP application program.
The current ABAP program "ZMSACCESS_DOWNLOAD1" had to be terminated because one
of the
statements could not be executed.
This is probably due to an error in the ABAP program.
Unable to perform database selection fully.
record.
What can you do?
If the error occurs in debugging mode, you should
first run the process without debugging activated.
If the error persists outside debugging, you must check the application
program more closely.
Print out the error message (using the "Print" function)
and make a note of the actions and input that caused the
error.
To resolve the problem, contact your SAP system administrator.
You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
This is probably because this FM is doind a commit work and hence the cursor connection the DB gets deleted.
Can you please take a look and advise if we can do anything beter,Thanks

Hi Gurus,
We are able to do download small amount of data successfully but the problem is with huge volume of data say for millions of records we can't read and store it in internal table as it is exceeding the memory and eventually going for dump.
If we use cursor or field symbols then if inside loop if we call that MS Access download FM the it is doing a database commit operation and that is closing the cursor. In the next run of the loop, it is going for run time error as commit inside loop throws run time exception in ABAP environment.
Looking for your help in this issue.
Thanks in advance.
