Hi Rakesh,
                This is the code for ur problem check it once.We have to use this code according to ur requirement ok..The compulsory condition is data is present in the internal table not in database table.If it is in database table move it to internal table first.And follow the below logic that will work fine 4 ur problem check it once.
*Local Variables
  DATA: lv_temp  LIKE sy-tabix.
CASE sy-ucomm.
*Fetch the FIRST Line from the Internal Table.
    WHEN 'FIRS'.
      READ TABLE gt_data INTO wa INDEX 1.
      lv_temp = sy-tabix.
*Fetch the NEXT Line from the Internal Table.
    WHEN 'NEXT'.
      lv_temp = lv_temp + 1.
      READ TABLE gt_data INTO wa INDEX lv_temp.
*Fetch the PREVIOUS Line from the Internal Table.
    WHEN 'PREV'.
      lv_temp = lv_temp - 1.
      READ TABLE gt_data INTO wa INDEX lv_temp.
*Fetch the LAST Line from the Internal Table.
    WHEN 'LAST'.
      READ TABLE gt_data INTO wa INDEX sy-tfill.
      lv_temp = sy-tfill.
