You have scoped for Demand Processing, that the format for the fields to be displayed in the Resource Scheduler Assignment bar is ABC (ABC is any set of fields selected for the display).
In the Resource Scheduler, the Assignment Bar displays the correct fields but the Tooltip for the mouse-over displays only the fields Time, Description and Account.
Reproducing the Issue
1. Go to workcenter Resource Scheduler.
2. Find any scheduled Assignment.
3. Note the format in the bar is ABC (this is correct as per finetuning).
4. Hover the mouse over the entry (enable the Tooltip in More > Settings if necessary).
->Result: the format in the tool tip is Time, Description, Account.
The fine tuning of the Assignment bar list of fields is currently supported only for the Assignment bar, not for the Tooltip.
We have this in planning for a future release.
