Ref: https://docs.oracle.com/en/cloud/saas/project-portfolio-management/19b/oapfm/project-foundation-configuration-define-project-resource-breakdown-structures.html#OAPFM180158_2 Why can't I find persons in the list of resources when I enter team members, planning resources, or person rate schedules?
You can't find persons in the list of resources when you enter team members, planning resources, or person rate schedules in the following situations:
The administrator didn't assign a department while creating users. Persons must have an active assignment and be assigned to a department in Oracle Fusion Human Capital Management before they can be added as team members or entered as resources on the planning resource breakdown structure or person rate schedule.
The resource isn't active in Oracle Fusion Human Capital Management because the current date is before the effective date of the resource. If you want to include persons who will start in the future, select the Include people with future-dated effective start dates option when you search for the person.
Persons assigned as project managers aren't active as of the project start date.
The assignment of the person is terminated, and an appropriate value isn't set for the number of days to display people with terminated assignments. You can set the profile value appropriately at the site profile level using the Specify Number of Days to Display People with Terminated Assignments task in the Setup and Maintenance work area.
