The Transformation Preparation Service (TPS) is a strategic offering from SAP designed to help customers at the beginning of their transformation journey. Its primary purpose is to bridge the gap between the customer's business objectives and the technical execution of the project. The service focuses on creating a clear transformation roadmap, defining the scope, and building a solid business case. This alignment ensures that the implementation strategy directly supports the desired business outcomes and accelerates the adoption and value realization of the acquired SAP software entitlements.

A. To train end-users on the new SAP system functionalities: This is incorrect. End-user training is a distinct activity that occurs later in the project lifecycle, typically within the Realize or Deploy phases of the SAP Activate methodology.

B. To develop custom extensions for the SAP Cloud ERP private edition: This is incorrect. The TPS is a strategic planning service, not a development or technical implementation service. Custom development is part of the execution phase.

D. To provide post-implementation support and maintenance: This is incorrect. Post-implementation support (e.g., SAP Enterprise Support) is an operational service that begins after the system goes live, not a preparatory service.
