PERFORMANCE ISSUE IN LOV(ORACLE FORMS)

Question

I have a requirement to populate an LOV in a Form Which is taking LOT of TIME (PERFORMANCE ISSUE)
the Record Group Query is as
select segment1 INVENTORY_ITEM ,
inventory_item_id,
description,
primary_uom_code,
decode(service_item_flag, 'Y', service_duration, NULL) service_duration,
service_duration_period_code,
shippable_item_flag,
Decode(bom_item_type ,
1,'MDL',2,'OPT',3,'PLN',4,
Decode( service_item_flag,'Y','SRV',
Decode( serviceable_product_flag,'Y','SVA','STD'))) item_type_code
from mtl_system_items_b --table name
where organization_id = :QOTLNDET_LINES.ORGANIZATION_ID
AND (bom_item_type = 1 or bom_item_type = 4)
AND vendor_warranty_flag = 'N'
AND primary_uom_code <> 'ENR'
AND ((:QOTLNDET_LINES.LINE_CATEGORY_CODE = 'ORDER' and customer_order_enabled_flag = 'Y') OR
(:LINE_CATEGORY_CODE = 'RETURN' and NVL(returnable_flag, 'Y') = 'Y'))
AND segment1 like :QOTLNDET_LINES.INVENTORY_ITEM || '%'
When ever i give :QOTLNDET_LINES.INVENTORY_ITEM from Front end This LOV need to be displayed.
IT IS TAKING MORE THAT 3 MINUTES DEPENDING ON THE ITEM GIVEN.
SUGGEST ME TO REDUCE THIS TIME.
Thanks,
Durga Srinivas

Answer 1

I had an idea ,
record_group1=
select segment1 INVENTORY_ITEM ,
inventory_item_id,
description,
primary_uom_code,
decode(service_item_flag, 'Y', service_duration, NULL) service_duration,
service_duration_period_code,
shippable_item_flag,
Decode(bom_item_type ,
1,'MDL',2,'OPT',3,'PLN',4,
Decode( service_item_flag,'Y','SRV',
Decode( serviceable_product_flag,'Y','SVA','STD'))) item_type_code
from mtl_system_items_b --table name
where organization_id = :QOTLNDET_LINES.ORGANIZATION_ID
AND (bom_item_type = 1 or bom_item_type = 4)
AND vendor_warranty_flag = 'N'
AND primary_uom_code 'ENR'
AND ((:QOTLNDET_LINES.LINE_CATEGORY_CODE = 'ORDER' and customer_order_enabled_flag = 'Y') OR
(:LINE_CATEGORY_CODE = 'RETURN' and NVL(returnable_flag, 'Y') = 'Y'))
AND segment1 like :QOTLNDET_LINES.INVENTORY_ITEM
Record_group2 =
select segment1 INVENTORY_ITEM ,
inventory_item_id,
description,
primary_uom_code,
decode(service_item_flag, 'Y', service_duration, NULL) service_duration,
service_duration_period_code,
shippable_item_flag,
Decode(bom_item_type ,
1,'MDL',2,'OPT',3,'PLN',4,
Decode( service_item_flag,'Y','SRV',
Decode( serviceable_product_flag,'Y','SVA','STD'))) item_type_code
from mtl_system_items_b --table name
where organization_id = :QOTLNDET_LINES.ORGANIZATION_ID
AND (bom_item_type = 1 or bom_item_type = 4)
AND vendor_warranty_flag = 'N'
AND primary_uom_code 'ENR'
AND ((:QOTLNDET_LINES.LINE_CATEGORY_CODE = 'ORDER' and customer_order_enabled_flag = 'Y') OR
(:LINE_CATEGORY_CODE = 'RETURN' and NVL(returnable_flag, 'Y') = 'Y'))
AND segment1 like :QOTLNDET_LINES.INVENTORY_ITEM || '%'
If i can give Full item name then dynamically I will assign Record_group1 else i will assign Record_group2 by using Set_LOV_Property()
so that if i give full item name lov is populated quickly .
Suggest me Which Triggers Should i use.
