RFC-XI-JDBC Scenario: Help with RFC code

Question

HI,
I am doing RFC-XI-JDBC Scenario, where I have to poll the contents of my Ztable in SAP to Oracle.
The appraoach i am using here is :
1. Created a FM with import parameters as the fields of my Ztable and without any  export parameter or source code.
2. Created a report to call that FM in background. The code of my report is as follows :
************************REPORT***********************************************************
Data:       it_zrfc_read_table type table of zrfc_read_table,
            wa_zrfc_read_table like line of it_zrfc_read_table.
PARAMETERS: tab_name like DD02L-TABNAME.
Data:       l_tabname type DD02L-TABNAME.
At selection-screen.
select single tabname from DD02L into l_tabname  where tabname = tab_name.
if sy-subrc <> 0.
  message 'incorrect table name' type 'E'.
endif.
start-of-selection.
select * from (tab_name) into corresponding fields of table it_zrfc_read_table.
loop at it_zrfc_read_table into wa_zrfc_read_table.
CALL FUNCTION 'ZRFC_READ_TABLE2XI'
IN BACKGROUND TASK DESTINATION 'ORACLEGIS_RFC_SENDER'
  EXPORTING
    valve_id       = wa_zrfc_read_table-valve_id
    equnr          = wa_zrfc_read_table-equnr
    ernam          = wa_zrfc_read_table-ernam
    invnr          = wa_zrfc_read_table-invnr
    groes          = wa_zrfc_read_table-groes
    elief          = wa_zrfc_read_table-elief
    gwlen          = wa_zrfc_read_table-gwlen
    gwldt          = wa_zrfc_read_table-gwldt
    serge          = wa_zrfc_read_table-serge
    typbz          = wa_zrfc_read_table-typbz.
    endloop.
    commit work.
NOw my problem is that although I am able to send a table with a single record, but when my records > 1, it is not able to poll.
Please guide me what can be altered in the code or any other suggestion.
Thanks,
Puneet

Hi,
Instead of calling RFC many times I would:
1) create RFM with only one import parameter
TYPE your_table type
2) call only once RFM in the report:
  CALL FUNCTION 'ZRFCNAME'
    IN BACKGROUND TASK
    DESTINATION 'RFCDEST'
    EXPORTING
      pt_table = i_table.
  COMMIT WORK AND WAIT.
This will also improve the performance.
