Can you format your code according to the sticky in the forum.

Also to even attempt at trying to tune a query please post the results from explain plan and tkprof.

Hi,It`s really tough to tune a query without execution plan or information on the objects being used.However,by a glance on the query I see the following joins
(QT.QT_CS_CODE='361'OR QT.QT_CS_CODE='391')AND
QT.QT_STATUS<=500 AND
QT.QT_TYPE='3' AND
QT.QT_OUT_OF_WAREHOUSE_DATE Is Null;

Try adding this as the from clause and make it an inline query,
say in your from clause something like this
************************************
From
(select QT.QT_CS_CODE Country,
QT.QT_REFERENCE_NUMBER "Order#",QT.QT_CONFIRM_DATE,
QT.QT_REQUESTED_DELIVERY_DATE , QT.QT_CUSTOMER_CODE,
QT.QT_STATUS,QT.QT_DELIVERY_CHANGE FDD,QT.QT_NUMBER,QT.QT_CBD_NUMBER,QT.QT_NUMBER
from DM_QUOTATIONS@ISMANZ A where
A.QT_STATUS<=500 AND
A.QT_TYPE='3' AND
A.QT_OUT_OF_WAREHOUSE_DATE Is Null) QT,
DM_PRODUCTS_IN_QUOTATION@ISMANZ PIQ,
DM_COMPONENTS_IN_QUOTATION@ISMANZ CIQ,
DM_SALES_PEOPLE@ISMANZ SP,
DM_QUOTATION_OTHER_DETAILS@ISMANZ QOD,
DM_CUSTOMER_BASIC_DETAILS@ISMANZ CBD,
SO_COST_CENTRES@ISMANZ CC,
DM_QUOTATION_ADDRESSES@ISMANZ QA,
DM_PRODUCT_SUB_GROUPS@ISMANZ PSG,
DM_PRODUCTS@ISMANZ PRD

WHERE
-------------------------------

Let know the execution plan of this query.

Thanks,
Raghava
