Method to find inspection characteristic number

Question

want to get the inspection lot with the average min max of the inspection characteristic.... is there any method for it
SELECT QAMRMERKNR QALSMATNR AVG( QAMRMITTELWERT ) AS AVG MAX( QAMRMITTELWERT ) MIN( QAMR~MITTELWERT )
SUM( QAMR~MITTELWERT ) COUNT( * )
INTO (QAMR-MERKNR, QALS-MATNR, JQAMR-AVG1, JQAMR-MAX1, JQAMR-MIN1, JQAMR-SUM, JQAMR-COUNT )
FROM  ( QAMR INNER JOIN QALS
        ON QAMRPRUEFLOS = QALSPRUEFLOS
        INNER JOIN QAMV
        ON QAMRPRUEFLOS = QAMVPRUEFLOS
       AND QAMRVORGLFNR = QAMVVORGLFNR
       WHERE QALS~WERK  IN S_WERKS AND
             QALS~MATNR IN S_MATNR AND
             QALS~CHARG IN S_CHARG
GROUP BY QALSMATNR QAMRMERKNR.
WRITE: /10(20) JQAMR-AVG1,
30(20) JQAMR-MAX1,
50(20) JQAMR-MIN1,
70(20) JQAMR-SUM,
90(20) JQAMR-COUNT.

Answer 1

the problem is if i take the column QALS-CHARG & QAMR-PRUEFLOS in the select condition then i have to take both of them in the group by clause and then i dont get the output as i require... i want to have minimum , maximum, average of all inspection characteristics,,, along with the lot number nd batch number of a material..
if any of the guru have a report on quality then do send it
