Key Terms used in this lesson
Main vs. Performing Work Center
The main work center is the one in the order header, the performing work center is the one in the order operation. RSH focuses on the performing work center.
Work Center with / without HR Assignment
Work centers can be created with or without HR assignment, i.e. with an HR organizational unit and personel numbers. To fully use the RSH functionality (and of other apps), it is recommended to work with an HR assignment.
Business User
Combination of SAP User, Personnel Number and Business Partner - mandatory for many Fiori Apps.
Basics
Resource Scheduling basically relies on the same master data as used in Standard Asset Management.
Therefore, the units of capacity used in Resource Scheduling are the Maintenance Work Centers used in Standard Asset Management.
Also, the different functions of work centers are the same as known in Asset Management:
- Main (= responsible) work center in the master record of equipment and functional location
- Main work center in a maintenance item
- Main work center in the header of a task list
- Performing work center in the operations of a task list
- Main work center in the order header
- Performing work center in the operations of an order

For use in Resource Scheduling, it is important that the Standard Available Capacity in the Capacity Header Data is defined.
Depending on how capacity planning is to be carried out, work centers can be set up in different ways.
Main vs. Performing Work Center
In RSH the focus is on the Performing Work Center, i.e. the work center in the order operation. This means that utilization values, available capacities etc. are always displayed for this work center, not the main work center.
If you want to use the Assign People function in the Maintenance Scheduling Board, you need to assign a so-called Work Center Team to the performing work center (via app Manage Teams and Responsibilities).
Work Centers with HR assignment
If you want to assign order operations to responsible persons in order to document who performs the operation, the work center must be set up with an HR assignment. This means that organizational units, positions and personnel numbers have to be imported from the HR system and assigned to the work center.

Work Centers without HR assignment
If you want to plan your maintenance orders on the work center level without using responsible persons the HR assignment is not necessary.
