I have defined g_t_zv7_cachemapping as following ::
DATA : BEGIN OF g_t_zv7_cachemapping OCCURS 0,
         kostl LIKE zv7_cachemapping-kostl,
         END OF g_t_zv7_cachemapping.
SELECT SINGLE kostl FROM zv7_cachemapping INTO g_t_zv7_cachemapping
           WHERE  auart = g_t_vbak-auart.

Shashank,
DATA : BEGIN OF g_t_zv7_cachemapping OCCURS 0,
AUART LIKE zv7_cachemapping-AUART,
kostl LIKE zv7_cachemapping-kostl,
END OF g_t_zv7_cachemapping.
If not g_t_vbak[] is initial.
SELECT auart kostl
  FROM zv7_cachemapping INTO table g_t_zv7
for all entries in g_t_vbak
WHERE auart = g_t_vbak-auart.
Endif.
sort : g_t_zv7 by auart , 
          g_t_vbak by auart.
loop at g_t_vbak.
  READ TABLE g_t_zv7 WITH KEY AUART = g_t_vbak-AUART
                                    BINARY SEARCH.
   IF sy-subrc eq 0.
   ENDIF.
endloop.
Pls. reward if useful
