Issue:
On a project, the Allocate From Estimates process fails when run for most team members.  The process returns an error stating "ERROR: System Error.  Contact System Administrator" but provide no other details.
Environment:
CA PPM 15.x and above
Cause:
If the duration of the project is more than 55 years, then this will cause a negative Average Allocation % value if the resource's allocation to the project is set to anything higher than zero hours.  When this condition occurs, the action "Allocate From Estimates" will fail for that resource.  
Resolution:
Check the project finish dates for any resource where the "Allocate from Esitmates" action fails.  Ensure that the project span is no larger than 54 years maximum.

Example:
A project had the Finish date set to 12/30/3033, when it s hould have been 12/30/2033.  This caused the issue to occur.  However, since the date format that displays only shows two digits for the year, it was not apparent that the Finish date was set incorrectly from this view.
