RFC Function Module

Question

Hello,
I am trying to get the records using RFC FM in IT_DATA[] using the following. But I am not getting any records in it. it_data is declared as (DATA: it_data   TYPE tab512 OCCURS 0 WITH HEADER LINE.)
  LOOP AT it_rseg_data.
  it_options-text = 'BELNR = '.
  CONCATENATE ' '' ' it_rseg_data-belnr '''  AND ' INTO objid.
  CONDENSE objid NO-GAPS.
  CONCATENATE it_options-text objid INTO it_options-text
  SEPARATED BY space.
  APPEND it_options.
  ENDLOOP.
IT_OPTIONS gets built with different values of BELNR from it_rseg_data table.
    For Ex. BELNR = 1234
                BELNR = 5678
PERFORM read_rbkp_belnr_details USING p_logsys bldat bldat_to.
FORM read_rbkp_belnr_details USING p_logsys LIKE rfcdes-rfcdest bldat bldat_to.
DATA: l_errflg TYPE char1. CLEAR: it_data.  REFRESH: it_data.
  CHECK NOT vt_fields[] IS INITIAL.
read data from backend
  PERFORM read_table_rbkp_for_belnr USING 'RBKP'
                                            p_logsys bldat bldat_to
                                           CHANGING l_errflg.
ENDFORM.    
FORM read_table_rbkp_for_belnr USING pi_tabname LIKE dd02l-tabname
                                     pi_logsys bldat bldat_to
                                     CHANGING pc_errflg.
  REFRESH it_data. CLEAR it_data.
   CALL FUNCTION 'RFC_READ_TABLE'
    DESTINATION PI_LOGSYS
    EXPORTING
      query_table          = 'RBKP'
    TABLES
      OPTIONS        = it_options
      fields               = vt_fields
      data                 = it_data
    EXCEPTIONS
      table_not_available  = 1
      table_without_data   = 2
      option_not_valid     = 3
      field_not_valid        = 4
      not_authorized      = 5
      data_buffer_exceeded = 6
      OTHERS               = 7.
  it_rbkp_data [] = it_data [].
Shall appreciate if anyone can tell me where I am doing wrong and how do I correct it.
Thks,
Hemal

I think problem is while creating the options internal table
LOOP AT it_rseg_data.
it_options-text = 'BELNR = '.
CONCATENATE ' '' ' it_rseg_data-belnr ''' AND ' INTO objid.
CONDENSE objid NO-GAPS.
CONCATENATE it_options-text objid INTO it_options-text
SEPARATED BY space.
APPEND it_options.
ENDLOOP.
Say for example if you are inserting for BELNR 1000 then after your loop
it looks like
BELNR = '1000' AND.
I think you need to remove the AND from the last record
