Hi,
Yes it is better to creat the structure with required field.
ZSTRCOMPTRACKSUMMARY     (is a structure)
(Structure is required if ur using only few field of a single table or fields from diffrent tables)
Use that structure in table parameters of  your RFC
CTDETAILS (Table parameters)    like ZSTRCOMPTRACKSUMMARY (is structure)
Through the program pass the values to table parametrs (table parameters work as import and export parameters)
then from that parameters update ur Ztable
Pls go through the code.
FUNCTION ZGET_COMPTRACK_SUMMARY_REPORT.
""Local Interface:
*"  IMPORTING
*"     VALUE(USERID) TYPE  ZUSERID
*"     VALUE(FROMDATE) TYPE  ZFROMDATE
*"     VALUE(TODATE) TYPE  ZTODATE
*"  TABLES
*"      CTDETAILS STRUCTURE  ZSTRCOMPTRACKSUMMARY
  DATA : BEGIN OF IT_COMPTRACKHEADER OCCURS 0,
          COMPTRACKDATE TYPE ZCOMPTRACKDATE,
          COMTRACKID TYPE ZCOMTRACKID,
          USERID TYPE ZUSERID,
          SMUID TYPE ZSMUID,
          BRANDID TYPE ZBRANDID,
         END OF IT_COMPTRACKHEADER.
  DATA:  IT_COMPTRACKDETAIL LIKE ZCOMPTRACKDETAIL OCCURS 0  WITH HEADER LINE.
Get COMTRACK Header details for the given user id and DCRDATE period
  SELECT * FROM ZCOMPTRACKHEADER INTO CORRESPONDING FIELDS OF TABLE  IT_COMPTRACKHEADER
                     WHERE COMPTRACKDATE BETWEEN FROMDATE AND TODATE.
  IF IT_COMPTRACKHEADER[] IS NOT INITIAL.
    SELECT * FROM ZCOMPTRACKDETAIL INTO TABLE IT_COMPTRACKDETAIL
                FOR ALL ENTRIES IN IT_COMPTRACKHEADER
                WHERE COMTRACKID = IT_COMPTRACKHEADER-COMTRACKID.
    SORT IT_COMPTRACKDETAIL BY COMTRACKID.
    LOOP AT IT_COMPTRACKDETAIL.
      READ TABLE IT_COMPTRACKHEADER WITH KEY COMTRACKID = IT_COMPTRACKDETAIL-COMTRACKID.
      SELECT SINGLE  BRANDFULLNAME FROM ZBRANDMASTER INTO CTDETAILS-BRAND WHERE BRANDID = IT_COMPTRACKHEADER-BRANDID.
      SELECT SINGLE COMPCATSHORTNAME FROM  ZCOMPCATMASTER INTO CTDETAILS-CATEGORY
      WHERE COMPCATEGORYID = IT_COMPTRACKDETAIL-COMPCATEGORYID.
Get SMU Name from the ID  *
      SELECT SINGLE STEXT FROM HRP1000 INTO CTDETAILS-ORGUNIT
              WHERE OBJID = IT_COMPTRACKHEADER-SMUID
                AND OTYPE EQ 'O'
                AND PLVAR EQ '01'
                AND BEGDA LE SY-DATUM
                AND ENDDA GE SY-DATUM.
Append details to the CTDETAILS structure
      CTDETAILS-COMPTRACKDATE = IT_COMPTRACKHEADER-COMPTRACKDATE.
      CTDETAILS-COMTRACKID = IT_COMPTRACKHEADER-COMTRACKID.
      CTDETAILS-USERID = IT_COMPTRACKHEADER-USERID.
      CTDETAILS-REMARKS = IT_COMPTRACKDETAIL-REMARKS.
      APPEND CTDETAILS.
      CLEAR CTDETAILS.
    ENDLOOP.
    SORT CTDETAILS BY BRAND CATEGORY.
  ENDIF.
ENDFUNCTION.
