Although the two Staffing Workspaces are separate, the 'Allocation Timeline' Widgets are using view options from the 'Staff Grid' workspace. Creating a Pie Chart or Bar Chart with Type = 'Sum' that uses a Time Scaled Value (TSV) is using the View Options settings from within the 'Staff Grid' workspace.
Expected Results: The Widget on 'Allocation Timeline' should show an allocation amount for Sum of Periods as defined on the View Options in the 'Allocation Timeline' Workspace.
Actual Results: The Widget on the 'Allocation Timeline' is using the allocation amount for Sum of Periods as defined on the View Options in the 'Staff Grid' workspace.
Release 16.0.1
DE63899 [Converted to a Story and tracked separately].
Workaround: Configure both workspaces 'View Options' to be the same and save views on both workspaces (views are saved separately).
Resolved in 16.0.2
The 'Allocation Timeline' now uses the settings in the View Options on that tab instead of the options on the 'Staff Grid' tab.
After this issue was resolved, a new issue was identified related to this functionality.
