What generates capacity requirements in a process order?

In the context of SAP Production Planning, capacity requirements in a process order are generated primarily by phases. Phases represent distinct stages within a process order that require a certain amount of capacity to execute the planned activities. Each phase may involve multiple operations that consume resources and require time to complete, directly impacting the capacity needed.

Phases help in organizing the manufacturing process by dividing it into manageable parts, allowing for better tracking and planning of the production activities. This division aligns resources with specific tasks that need to be performed, helping to ensure that the production capacity is properly aligned with the demands of the phases.

While activities and operations are indeed essential components of the production process, it is the phases that act as the higher-level organizational unit from which capacity requirements can be derived. Resources, on the other hand, refer to the tools, equipment, or personnel needed to execute those operations or activities but do not independently generate capacity requirements without being linked to specific phases or operations.
