Performance Issue On Import Items INCOIN With MTL_SYSTEM_ITEMS_INTERFACE And MTL_PARAMETERS
Symptoms
ACTUAL BEHAVIOR
The is a performance issue with Import Items where the 5 most expensive script take up 97% of the time:
SELECT DISTINCT MSII.COPY_ORGANIZATION_CODE

MTL_SYSTEM_ITEMS_INTERFACE MSII, MTL_PARAMETERS MP WHERE MSII.PROCESS_FLAG =
1 AND MSII.SET_PROCESS_ID = :B3 AND MSII.TRANSACTION_TYPE = 'CREATE' AND

UNIT_OF_MEASURE FROM MTL_UNITS_OF_MEASURE MUOM WHERE UOM_CLASS = :B2 AND
MSI.PRIMARY_UOM_CODE = MUOM.UOM_CODE)
EXPECTED BEHAVIOR
Expect import items to run faster.
STEPS
The issue can be reproduced at will with the following steps:
1. Launch custom process that loads 5000 items at a time and launches Import Items
2. Observe trace file / log file and run time.
