SAP Cloud ALM for Implementation is the designated application lifecycle management tool for SAP S/4HANA Cloud Public Edition projects. It is designed to guide the implementation team through the project by providing a pre-configured workspace based on the SAP Activate methodology. The tasks and deliverables from the selected SAP Activate Roadmap are loaded directly into SAP Cloud ALM, where they can be assigned to team members, tracked, and executed. This provides a central platform for managing the entire implementation project, from the Prepare phase through to Deploy.

A. SAP Central Business Configuration: This tool is used for scoping business processes and performing configuration activities, but it is not the primary tool for managing or accessing the overall project tasks from the roadmap.

B. SAP Cloud ALM for Service: This component of SAP Cloud ALM is focused on the post-go-live phase, specifically managing service delivery, incident resolution, and ensuring business continuity, not implementation tasks.

D. SAP Cloud ALM for Operations: This component of SAP Cloud ALM is used after the system is live. It focuses on monitoring, alerting, and maintaining the health and performance of the cloud solution.

2. SAP Activate Roadmap Viewer, "SAP S/4HANA Cloud Public Edition (3-system landscape)": In the "Prepare" phase, the deliverable "Project Management" includes the task "Set Up Project in SAP Cloud ALM." This task explicitly states: "The project is set up in SAP Cloud ALM to manage the scope, schedule, budget, resources, and tasks." This directly links the roadmap tasks to management within SAP Cloud ALM.

3. SAP Help Portal, SAP S/4HANA Cloud, "Implementation Tools for 3-System Landscape": The official documentation outlines the toolset for the 3-system landscape. It positions SAP Cloud ALM as the tool for "Project and Task Management" and SAP Central Business Configuration for "Business Configuration." This clearly separates the roles of the two systems.
