Issue/Introduction

When looking at the 'Availability' field for a Resource in the Staffing Workspace and using the 'Grand Total' View Option, you see a really large number: 374,480 hours. 

 

Is this the maximum number of hours for a resource and why is it so large?

Environment

Release : Any

Resolution

• All Time Slice Curve data within Clarity have minimum and maximum date boundaries of Jan. 1, 1900 to Jun. 3, 2079. 
• The Grand Total 'Availabilty' hours for a Resource using the default, stock Standard Calendar without the Hire or Termination date will have a maximum number of hours = 374,480.  This is because the 'Availability' curve will have a (minimum) start date of Jan. 1, 1900 and a (maximum) end date of Jun. 3, 2079.  This equates to approximately 179 years. 
  • 374,480 total hours / 8 hours per day = 46,810 working days
  • 46,810 days / approximately 261 working days per year = approximately 179 years
• If you enter a Date of Hire and/or a Date of Termination, the Grand Total Availability will be adjusted upon update of time slices. 
• If you set up calendar shifts to alter the daily 'Availability Rate' and alter the calendar working days and non-working days, the Grand Total Availability will be adjusted upon update of time slices. 
• When viewing 'Sum of Periods' the Resource 'Availability' will be bound by the date range selected within the View Options.
