Restricting records in the select statement

Question

Hi,
I have one requirement where in i need to restrict my select statement to get only 250 records in the output table.
Here are the select statements i am using....
    SELECT a~ebeln
                 a~lifnr
                 a~ekgrp
                 b~werks
                 b~matnr
           FROM ekko AS a INNER JOIN ekpo AS b
           ON aebeln = bebeln
           INTO TABLE i_ekko
           WHERE a~ebeln IN r_ebeln AND
                        a~lifnr IN r_lifnr AND
                        a~ekgrp IN r_ekgrp AND
                        b~werks IN r_ewerk AND
                        b~matnr IN r_matnr AND
                        a~bstyp = 'F'.
            IF NOT i_ekko[] IS INITIAL.
Select Vendor name
           SELECT lifnr
                        name1
                  FROM lfa1
                  INTO TABLE i_lfa1
                  FOR ALL ENTRIES IN i_ekko
                  WHERE lifnr = i_ekko-lifnr.      
Here if i restrict the first select statement to get only 250 records then i am not getting the desired record in the second select statement.
Could anyone let me know how to write the select statement.
Regards,
Ramesh

Answer 1

restric the first select using up to 250.
sort the i_ekko by vendor name.
ex: sort i_ekko by lifnr.
use second select statement here.
