Re: Same select max is very slow in one program but fast in another

Hi Liu,

Index creation is not a advisable solution.Please follow the existing indexes by adding Mandt field.

Try like this

SELECT MAX( mkpf~budat )

              FROM mkpf

    INNER JOIN mseg

                   ON mseg~mblnr = mkpf~mblnr AND mseg~mjahr = mkpf~mjahr

                INTO posting_date

           WHERE mseg~mandt = sy-mandt

                  AND mkpf~mandt = sy-mandt

                  AND mseg~werks  = w_matl-batch_reservations-werks

                 AND mseg~charg  = w_matl-batch_reservations-charg

                 AND mseg~bwart  IN ('261', 'Z61').

Hope it will be helpful.

Regards,

Kannan
