1.  The Planning Manager (MRCRLF) and Master Schedule Interface Load (MRCSLW ) sometimes error out, getting error ORA-00001 while inserting to table MRP_SCHEDULE_DATES on index
MRP_SCHEDULE_DATES_U1. The trace files of the 2 concurrent requests are running the same sql at
the same time which appears to be causing the error due to overlapping concurrent requests:

INSERT INTO mrp_schedule_dates
(inventory_item_id, reference_schedule_id, organization_id,
schedule_designator, schedule_level, schedule_date,
last_update_date, last_updated_by, creation_date, created_by,
last_update_login, schedule_quantity, schedule_origination_type,
repetitive_daily_rate, source_forecast_designator, rate_end_date,
mps_transaction_id, schedule_comments, source_organization_id,
source_schedule_designator, schedule_workdate,
original_schedule_quantity, supply_demand_type)

When checking the mrp_schedule_interface table for duplicate records,
A>  Some cases does not find any rows returned
BUT
B> Other cases have been reported where rows in process_status = 3 did have duplicate Transaction_id's

select transaction_id, process_status, count(*)
from mrp_schedule_interface
Group by transaction_id, process_status having count(*)>1;
