Inner Join Select query

Question

hello all,
Below is a inner join query
    SELECT aebeln aebelp apackno bzekkn b~ps_psp_pnr
                 FROM ( ( ekpo AS a INNER JOIN ekkn AS b
                          ON aebeln = bebeln
                          AND  aebelp = bebelp )
                         INNER JOIN prps AS c
                          ON bps_psp_pnr = cpspnr )
                 INTO TABLE t_wbspo
                  WHERE a~ebeln IN s_ebeln
                   AND  c~psphi IN s_psphi
                   AND  stufe = c_task.
I want to modify this select and put one more join on ekkn-aufnr
and aufk-afunr .
Now for this i write the below code
  SELECT aebeln aebelp apackno bzekkn bps_psp_pnr baufnr
           FROM ( ( ( ekpo AS a INNER JOIN ekkn AS b
                    ON aebeln = bebeln
                    AND  aebelp = bebelp )
                   INNER JOIN prps AS c
                    ON bps_psp_pnr = cpspnr )
                    INNER JOIN aufk AS d
                    ON baufnr = daufnr )
           INTO TABLE t_wbspo
            WHERE a~ebeln IN s_ebeln
             AND  c~psphi IN s_psphi
             AND  d~aufnr IN s_aufnr
    AND  stufe = c_task.
By the above way does it puts a join on ekkn-aufnr and aufk-aufnr ?
Is the above way the right way to do it ?
Please confirm
regards
