BSIS performance

Check for duplicates

SELECT zuonr

budat

wrbtr

FROM bsis

into table i_bsis

for all entries in i_indata1

WHERE bukrs = 'BP01' and

gjahr = sy-datum+0(4) and

budat = i_indata1-t_pdate AND

zuonr = i_indata1-t_kioid.

When i am trying to select data from bsis i get time out error. Is there a way to avoid this?
