SAP HANA - Inner Join Performance Optimization

Hi,

I have below sql statement. I would like to see if I can optimize the performance of it, as it is currently taking around 7 minutes to execute.

Any ideas on how I can improve the performance?

/BIC/ANSD300000 contains around      189.5 mio records

/BI0/MCUST_SALES contains around      1.7 mio records

/BIC/ANSD260000 contains around           7.5 mio records

SELECT s."/BIC/CUSHIER6", b."MATERIAL", b."BILL_DATE", b."NETVAL_INV" * b."BILL_QTY" as "Lastest NIP"

FROM

            ( ( "/BIC/ANSD300000" as b inner join "/BI0/MCUST_SALES" as s on                      

                         b."SOLD_TO" = s."CUST_SALES" and

                         b."DISTR_CHAN" = s."DISTR_CHAN" and

                         b."DIVISION" = s."DIVISION" and

                         b."SALESORG" = s."SALESORG" )

                         inner join "/BIC/ANSD260000" as o on

                                     b."DOC_NUMBER" = o."DOC_NUMBER" )

WHERE

            o."DOC_TYPE" = 'ZOR' and

            b."BILL_TYPE" = 'ZF2' and           

            s."DATETO" = '99991231' and

            b."DISTR_CHAN" = '01'

ORDER BY s."/BIC/CUSHIER6", b."MATERIAL", b."BILL_DATE" desc;

Thanks in advance.
