To set up an organizational structure for a new implementation, the following options are possible:
Assign an employee to several organizational units. This is possible by using the Employee Assignment function in the Organizational Management work center. An employee can be assigned to multiple organizational units with different validity periods and functions. For example, an employee can be a sales representative in one unit and a service agent in another unit.
Use the Reporting Line function for selection. This is possible by using the Reporting Line function in the Organizational Management work center. This function allows the administrator to select an organizational unit and display its reporting line, which shows the hierarchical relationship between the unit and its parent and child units. The administrator can also edit the reporting line by adding, removing, or changing the position of the units.
