Joining WIP_DISCRETE_JOBS to a Bill Of Materials table - sql

Question

I have an SQL query in which I am trying to fetch items along with their components which have Bill Of Materials (BOM) enabled and whose creation date is withing the last three years.
The problem is every item along with their component list gets repeated. Suppose an item has 5 components, and I query with the particular item number. I get 35 rows (7 repetitions of sets of 5 components). However, if I query with a particular WIP_ENTITY_NAME or if I use DISTINCT, I get a perfect 5 rows of data. I need to get this data (5 rows, no repetitions) when I query with a particular item number.
Here is the query:
SELECT *
FROM BOM_BILL_OF_MATERIALS BOM,
BOM_INVENTORY_COMPONENTS BIC,
BOM_COMPONENTS_B BCB,
BOM_OPERATIONAL_ROUTINGS_V BORV,
BOM_OPERATION_SEQUENCES_V BOSV,
BOM_STRUCTURES_B BSB,
BOM_STRUCTURE_TYPES_B BST,
MTL_SYSTEM_ITEMS_B MSI,
MTL_SYSTEM_ITEMS_TL MSIT,
ORG_ORGANIZATION_DEFINITIONS OOD,
WIP_DISCRETE_JOBS_V WDJV
WHERE BOM.BILL_SEQUENCE_ID = BIC.BILL_SEQUENCE_ID
AND BIC.COMPONENT_SEQUENCE_ID = BCB.COMPONENT_SEQUENCE_ID
AND BCB.BILL_SEQUENCE_ID = BSB.BILL_SEQUENCE_ID
AND BOM.STRUCTURE_TYPE_ID = BST.STRUCTURE_TYPE_ID
AND BOM.ASSEMBLY_ITEM_ID = MSI.INVENTORY_ITEM_ID
AND BOM.ORGANIZATION_ID = MSI.ORGANIZATION_ID
AND BOSV.ROUTING_SEQUENCE_ID = BORV.ROUTING_SEQUENCE_ID
AND BORV.ASSEMBLY_ITEM_ID = BOM.ASSEMBLY_ITEM_ID
AND BORV.ORGANIZATION_ID = BOM.ORGANIZATION_ID
AND MSI.INVENTORY_ITEM_ID = MSIT.INVENTORY_ITEM_ID
AND MSI.ORGANIZATION_ID = MSIT.ORGANIZATION_ID
AND MSIT.ORGANIZATION_ID = OOD.ORGANIZATION_ID
AND MSIT.LANGUAGE = USERENV('LANG')
AND sysdate BETWEEN BCB.EFFECTIVITY_DATE AND NVL(BCB.DISABLE_DATE, sysdate)
AND MSI.BOM_ENABLED_FLAG = 'Y'
AND NVL(MSI.ENABLED_FLAG,'X') ='Y'
AND OOD.ORGANIZATION_ID IN (203,204,328)
AND BORV.COMMON_ROUTING_SEQUENCE_ID = WDJV.COMMON_ROUTING_SEQUENCE_ID
AND BORV.ASSEMBLY_ITEM_ID = WDJV.PRIMARY_ITEM_ID
AND WDJV.CREATION_DATE > ADD_MONTHS( sysdate, -12*3 )
AND WDJV.WIP_ENTITY_NAME = '28799'
--and MSI.SEGMENT1='9064090'
Also, I have found that the sets of 5 differ from each other on the basis of their WE_ROW_ID, REQUEST_ID_7, SCHEDULED_START_DATE, SCHEDULED_COMPLETION_DATE and other columns which are present in the WIP_DISCREET_JOBS table. Is there any way to map these columns to any of the BOM tables? I am new to this, so please bear with me gurus.

I see you are asking about the Oracle e-Business Suite data model.
trying to fetch items ... and whose creation date is withing the last three years.
That is not what your query is doing. You are getting details of items made (via a WIP discrete job) within the last 3 years -- and you are getting a duplicate of the item for every time it was made (i.e., every occurrence in WIP_DISCRETE_JOBS_V).
If you want items made in the last 3 years, but you only want each item once, you should use an EXISTS (semi-join) to filter the rows instead of actually joining to WIP_DISCRETE_JOBS_V, which will cause duplicates). Something more along these lines:
SELECT *
FROM bom_bill_of_materials bom,
bom_inventory_components bic,
bom_components_b bcb,
bom_operational_routings_v borv,
bom_operation_sequences_v bosv,
bom_structures_b bsb,
bom_structure_types_b bst,
mtl_system_items_b msi,
mtl_system_items_tl msit,
org_organization_definitions ood --,
--wip_discrete_jobs_v wdjv
WHERE bom.bill_sequence_id = bic.bill_sequence_id
AND bic.component_sequence_id = bcb.component_sequence_id
AND bcb.bill_sequence_id = bsb.bill_sequence_id
AND bom.structure_type_id = bst.structure_type_id
AND bom.assembly_item_id = msi.inventory_item_id
AND bom.organization_id = msi.organization_id
AND bosv.routing_sequence_id = borv.routing_sequence_id
AND borv.assembly_item_id = bom.assembly_item_id
AND borv.organization_id = bom.organization_id
AND msi.inventory_item_id = msit.inventory_item_id
AND msi.organization_id = msit.organization_id
AND msit.organization_id = ood.organization_id
AND msit.language = USERENV ('LANG')
AND SYSDATE BETWEEN bcb.effectivity_date AND NVL (bcb.disable_date, SYSDATE)
AND msi.bom_enabled_flag = 'Y'
AND NVL (msi.enabled_flag, 'X') = 'Y'
AND ood.organization_id IN (203, 204, 328)
--AND borv.common_routing_sequence_id = wdjv.common_routing_sequence_id
--AND borv.assembly_item_id = wdjv.primary_item_id
--AND wdjv.creation_date > ADD_MONTHS (SYSDATE, -12 * 3)
--AND wdjv.wip_entity_name = '28799'
AND EXISTS ( SELECT 'discrete job within the last 3 years'
FROM wip_discrete_jobs_v wdjv
WHERE wdjv.common_routing_sequence_id = borv.common_routing_sequence_id
AND wdjv.primary_item_id = borv.assembly_item_id
AND wdjv.creation_date >= ADD_MONTHS(SYSDATE, -12*3)
)
--and MSI.SEGMENT1='9064090'
Note -- I kept this as close to your original query as possible and I didn't verify all the join conditions you used. So there may be some other bugs in your initial query that I have inadvertently duplicated.
One other thing, it's not a good practice to use the forms views, like WIP_DISCRETE_JOBS_V or BOM_OPERATIONAL_ROUTINGS_V. These views are to provide data to online forms. Not only can your performance suffer (because they contain joins that you may not need), but, if you go to Oracle's eTRM site (http://etrm.oracle.com/pls/etrm/etrm_pnav.show_object?c_name=BOM_OPERATIONAL_ROUTINGS_V&c_owner=APPS&c_type=VIEW), you will see this warning:
Warning: Oracle does not recommend you query or alter datausing this
view. It may change dramatically in subsequent minor or major
releases.
It is better to SELECT from the base tables.
