Why can't I see resource or territory hierarchy or forecast data?
As a sales administrator, you must be assigned a data security policy for the Sales Administrator role or an equivalent custom job role to view resource and territory hierarchies and forecast data from the Forecast overview page.
You can edit a copy of the Sales Administrator role from the Security Console and add the
Sales Forecast (FSF_DS_PARTICIPANTRF_DN_VIEW) security policy to
the role. Select All values from the Data
Set drop-down list and from the Actions menu,
enable all 3 menu items and select OK.
