Hi John,
Here is my first query :-
SELECT AW.PACKAGELEAD,
SUBSTR(AW.DEVICENO,1,50),
AW.CURR_OPER,
AW.CURQTY,
AW.OPERATION_SEQ_NUM,
AW.CUSTOMERCODE, ARC.ATTRIBUTE2, AW.DEVICENO DEVICE_NO, BSO.OPERATION_DESCRIPTION, AW.INVENTORY_ITEM_ID
FROM AIC_COST_WIP_TEMPB AW, AR_CUSTOMERS ARC, BOM_STANDARD_OPERATIONS BSO
WHERE ARC.ATTRIBUTE1 = AW.CUSTOMERCODE
AND ARC.STATUS = 'A'
AND BSO.OPERATION_CODE(+) = AW.CURR_OPER
ORDER BY AW.DEVICENO, AW.CURR_OPER
and here is the second query :-
SELECT DISTINCT MSIK2.CONCATENATED_SEGMENTS,
BBOM.ASSEMBLY_ITEM_ID,
BIC.OPERATION_SEQ_NUM,
CST.MATERIAL_COST,
BIC.COMPONENT_QUANTITY,
TO_NUMBER(BIC.attribute1) CPY
FROM BOM_BILL_OF_MATERIALS BBOM,
     BOM_INVENTORY_COMPONENTS BIC,
     MTL_SYSTEM_ITEMS_KFV MSIK2,
CST_ITEM_COST_TYPE_V CST
WHERE BBOM.BILL_SEQUENCE_ID = BIC.BILL_SEQUENCE_ID     
AND BIC.component_item_id = MSIK2.inventory_item_id
AND MSIK2.INVENTORY_ITEM_ID = CST.INVENTORY_ITEM_ID
AND CST.ORGANIZATION_ID = 8
AND MSIK2.ORGANIZATION_ID = 8
AND cst.cost_type_id = 1
AND (BIC.disable_date IS NULL OR (BIC.disable_date - SYSDATE) > 0)
the link between two qeuery is the query1->inventory_item_id & operation_seq_num versus query2->assembly_item_id & operation_seq_num.
The both link is working fine. However, I need to show the results of formula and also cumulative of the results. But the result will only be shown if there is a link found between the two query, even I have putting null value as zero if it does not found from the query. So, that's my problem.
Hope u can understand and help me to resolve this problem. Thanks
