Symptoms

ACTUAL BEHAVIOR
While running an ETL for a P6 datasource, the ETL execution takes a long time to complete.

The HistRollupActivity task runs the following SQL:

Within the package procedure, the following update statement is being run:

  UPDATE w_activity_history_f wahf
  SET (wahf.bl_actual_labor_units
  , wahf.bl_actual_nonlabor_units
  , wahf.bl_actual_labor_cost
  , wahf.bl_actual_nonlabor_cost
  , wahf.bl_actual_material_cost
  , wahf.bl_actual_expense_cost
  , wahf.bl_actual_total_cost)
  = (SELECT
  SUM(wasf.bl_actual_labor_units)
  , SUM(wasf.bl_actual_nonlabor_units)
  , SUM(wasf.bl_actual_labor_cost)
  , SUM(wasf.bl_actual_nonlabor_cost)
  , SUM(wasf.bl_actual_material_cost)
  , SUM(wasf.bl_actual_expense_cost)
  , SUM(wasf.bl_actual_total_cost)
  FROM w_activity_spread_hf wasf
  WHERE wasf.activity_wid = wahf.activity_wid AND wasf.datasource_id = wahf.datasource_id AND wasf.datasource_id = vsrc_id
  )
  WHERE wahf.day_wid = dayRowWid AND wahf.datasource_id = vsrc_id AND wahf.project_object_id = proj.project_object_id;

Above Statement repeats for:

EXPECTED BEHAVIOR
Identify tuning to the SQL which is executed within the hist_rollup_pkg.rollup_to_activity_history package procedure for improving the overall duration of a P6 datasource ETL (and specifically, the HistRollupActivity task from PROC_AFTER_LOADING_PKG_SCD Scenario)

STEPS
The issue can be reproduced at will with the following steps:
1. Login to the Analytics Administration application
2. Note the amount of time it takes for a P6 ETL to complete.

ADDITIONAL INFORMATION
This issue is occurring within production.
