Hi Deepthi,
You can do as per below:
1) Select the required entries from the tables you need (VBAK, VBAP, KNA1, etc)
SELECT VBELN ERDAT KUNNR
    into table it_vbak
    from VBAK
where VBELN = S_VBELN. "Selection criteria
If sy-subrc = 0.
SELECT VBELN POSNR MATNR
    into table it_vbap
    from VBAP
for all entries in it_vbak
where VBELN = it_vbak-vbeln
SELECT KUNNR NAME1
    into table it_vbak
    from VBAK
where VBELN = it_vbak-vbeln.
endif.
2) Loop at the entries, and read internal table it-kna1 for customer info.
Loop at it_vbak into wa_vbak.
read table it_kna1 into wa_kna1 with key kunnr = wa_vbak-kunnr.
if sy-subrc = 0.
endif.
loop at it_vbap into wa_vbap where vbeln = wa_vbak-vbeln.
endloop.
endloop.
This is the basic idea and short example of how to extract entries and read internal table.
Hope this helps.
