Which statements about user modes are true?

User modes in SAP S/4HANA are essential for managing how multiple users interact with the system, especially when it comes to accessing and modifying master records.

The first statement reflects the locking mechanism in the SAP system. When a user accesses a master record to make changes, the system locks that record to prevent simultaneous edits by another user. This is crucial to maintain data integrity and ensure that one user's changes do not conflict with another's.

The second statement highlights the limitation placed on user modes. By default, the system can have a maximum of six modes open simultaneously. This constraint helps maintain system performance and ensures that users can manage their sessions effectively without overwhelming the system with too many concurrent requests.

The third statement points to the potential issue that arises when multiple modes are opened. If a user tries to edit master data while other modes are open—especially if they are accessing the same master record—this can lead to user blocks. These blocks prevent users from altering records until the session is released, which can lead to delays and inefficiencies in operations.

Collectively, these statements underscore the importance of understanding user modes within the Sourcing and Procurement framework in SAP S/4HANA. They illustrate how the system manages user access and data integrity and highlight
