     vekp~service
     COUNT( DISTINCT vekp~shipment )
     SUM( vekp~packagecount )
     SUM( vekp~rate ) FROM vekp
  INNER JOIN tab
  ON tab~carrier = vekp~carrier INNER JOIN likp
  ON vekp~delivery = likp~vbeln INTO itab

        vekp~delivery = likp~vbeln AND
        vekp~carrier = tab~code
        GROUP BY vbeln shiptype carrier service.

You don't need to select from the table in order to join on it, just add VBUK to your join.

I notice that you haven't included an INTO clause, which is needed when you use a field-list.

Something like:

SELECT likp~vbeln
 tab~shiptype
 vekp~carrier
 vekp~service
 COUNT( DISTINCT vekp~shipment )
 SUM( vekp~packagecount )
 SUM( vekp~rate ) 
INTO (field1, fied2, etc)                    "<=== Change1
FROM vekp
INNER JOIN tab
  ON tab~carrier = vekp~carrier INNER JOIN likp
  ON vekp~delivery = likp~vbeln INTO itab
INNER JOIN VBUK                              "<=== Change2
  ON likp~vbeln = vbuk~vbeln
WHERE likp~erdat IN so_date AND
    vekp~delivery = likp~vbeln AND
    vekp~carrier = tab~code AND
    vbuk~fieldtocheck = 'C'                  "<=== Change3
GROUP BY vbeln shiptype carrier service.
