Really urgent: reagrding alv format for like (internal tables)

Question

Hi,
I making a report in which i am using the concept of 2 internal tables and i am usnig the concept of likes in a internal table .
for instance,
DATA : BEGIN OF ITAB OCCURS 0,
          ITEMID LIKE CHVW-MATNR,      
          WERKS LIKE CHVW-WERKS,   
          CHARG LIKE CHVW-CHARG,       
          SHKZG LIKE CHVW-SHKZG,       
          MENGE LIKE CHVW-MENGE,     
          MEINS LIKE CHVW-MEINS, 
END OF ITAB.
DATA: BEGIN OF ITAB1 OCCURS 0,
           MATNR TYPE BSEG-MATNR,  
           LIFNR TYPE BSEG-LIFNR,       
           AUGDT TYPE BSEG-AUGDT,     
           WRBTR TYPE BSEG-WRBTR,      
         END OF IT_BSEG.
and i am able to create ALV for 1 itab only as i had declared all fields in a 1 itab ,but now i have to declare 1 more itab and i  dont know how to perform ALV with 2 itabs..
Plzz help me out as it is really urgent to me.

Hi Ric,
Yes, You can .
Check the sample ALV  program which helps u in displaying output using ALV . Comments have been made everywhere .
report  zvenkat_alv_2_grid_description.
types:
      begin of t_mard,
       werks type mard-werks,
       lgort type mard-lgort,
       matnr type mard-matnr,
       insme type mard-insme,
       einme type mard-einme,
       speme type mard-speme,
      end of t_mard.
data:
      w_mard type t_mard.
data:
      i_mard type standard table of t_mard.
" ALV Declarations
