What function do workflows serve in SAP MDG?

Workflows play a crucial role in SAP MDG by facilitating the automation of processes related to data approval and validation. This is essential in ensuring that data changes go through a structured review and approval mechanism before being finalized in the system. By automating these processes, workflows help to enhance efficiency, eliminate manual interventions, and reduce the risk of errors that may arise from inconsistent data handling.

In the context of SAP MDG, workflows are designed to manage tasks such as assigning responsibilities to different users or groups, sending notifications, and tracking the progress of data changes. This ensures that all relevant stakeholders are involved in the data governance process and that there is a clear audit trail for every modification made.

The other options are important components in different areas of SAP but do not relate to the specific function of workflows in MDG. User access management and documentation of historical changes are relevant in the context of data governance but do not encapsulate the automated and procedural nature of workflows within the MDG framework. Similarly, overseeing hardware installations is a function unrelated to data management processes.
