To assign employee to jobs or positions:
1. Use the Enter Person window to assign employees to jobs or positions. If you are not using position approval hierarchies for document routing, you must provide the employee’s supervisor.

2. Before you can reference your position hierarchies in Purchasing, you must run the Fill Employee Hierarchy process. This process creates an employee–populated representation of your approvals hierarchy and should be run whenever you make a structural or personnel change to your hierarchies or assignments. You can set up this process to run automatically at predefined intervals.
The process creates an error log which lists all positions to which no employee is assigned, but having such positions is a benign
error that does not hamper system operation.
