Checking for data in tables

Question

hi gurus,
i have an itab which has fi transactional data , which inlcudes glaccounts with the name belnr.
now i need to check if each glaccount has a master data , if a match is not found that glaccounts must be stored to display later.
so i thought of doing this way, is it a best practise to do this way.
tables: skb1.
data : i_skb1 like skb1 occurs 0 with header line.
data:begin of i_saknr occurs 0,
saknr like skb1-saknr,
end of i_saknr.
loop at itab.
select single * from skb1 into i_skb1 where saknr EQ itab-belnr.
if sy-subrc <> 0.
i_saknr-saknr = itab-belnr.
append i_saknr.
endif.
endloop.
is there a better way of doing this.

Sanjana,
Do like this
tables: skb1.
data : i_skb1 like skb1 occurs 0 with header line.
types:begin of ty_saknr,
saknr like skb1-saknr,
end of ty_saknr.
data: i_saknr type table of ty_saknr,
        wa_saknr type ty_saknr.
select * from skb1 into table i_skb1 for all entries in itab where saknr EQ itab-belnr.
loop at itab into wa.
read table itab into wa with key saknr = wa-belnr.
if sy-subrc <> 0.
wa_saknr-saknr = wa-belnr.
append wa_saknr to i_saknr.
endif.
endloop.
