You are using the Manage Workforce app to perform the first tasks of Identity and Access Management (IAM) on SAP S/4HANA Cloud, public edition:
- Create workforce users
- Assign business users
The Manage Workforce app creates and updates worker information for employees and contingent workers, including work agreements and changing employment situations. This app enables you to upload/edit employee information independent of an HR system of record.

During an implementation project, you use the Manage Workforce app to create business users for the project team members in the SAP S/4HANA Cloud starter system and the initial users in the development, test, and production systems.
When creating the associated business user as the admin, you switch from the Manage Workforce app to the Maintain Business Users app. When you return from the Maintain Business Users app to the Manage Workforce app, the business user is automatically assigned to the worker.
In SAP S/4HANA Cloud, public edition, a Business User must be assigned as a Worker (it could be an Employee or Contingent Worker type). Once integrated with a customer’s HR system (for example, SAP SuccessFactors Employee Central), the Manage Workforce app becomes read only to ensure only one HR data source. Changes to users must be made directly in the HR system of record after the integration is activated.
