You can see the Allocation total (sum of periods or grand total) values on the 'Allocations Timeline' workspace for both Allocations by Investments (I-R) or Allocations by Resources (R-I). However, if you add other Staff TSV Total fields listed below, you see zeros. The values are shown in the 'Staff Grid' workspace.
Expected Results: You should see the 'Total' (Sum of Periods, Grand Totals) value for the staffing TSV fields: Actuals, ETC, Total Usage, Hard Allocation, Remaining Allocation, Remaining Availability.
Actual Results: You see zeros for these fields.
This is identified as a functional gap in the new workspace introduced in 16.0.1. This functionality is under review for inclusion in the future.
Workaround: Use the 'Staff Grid' workspace to see these values for Sum of Periods or Grand Totals as configured in the View Options.
Resolved in 16.0.2
