Expected Result: The incremental Load Data Warehouse job completes successfully

Check for project task duplication with query:
select TASK_KEY, INVESTMENT_KEY, COUNT(1)
where clarity_updated_date >= to_date('1910/01/01 00:00:00', 'yyyy/mm/dd HH24:MI:SS')
group by TASK_KEY,INVESTMENT_KEY
having COUNT(*) > 1
If results are returned, go to the duplicated tasks
and click the Action > Update Cost Totals
This will fix the duplication and allow the full Load DWH job to complete.
