Introduction:
CA Dynamic Capacity Intelligence (DCI) GUI Sim CG report page shows the following table:
Sim CG GUI table page
so the values for R4HA, C4HA and Sim C4HA are identical at the single interval level.

The graph page confirms that the values are identical at the single interval level.

Question:
Why are the above values always the same for each interval?
Environment:
CA Dynamic Capacity Intelligence GUI
Answer:
If a Defined Capacity is set below the real R4HA, the sub capacity report uses the value for defined capacity.
DCI shows that value as "Sim C4HA", the simulated capped 4-hour average.
