For which planning-relevant data objects do you set just one indicator to include then in PP/DS?

The correct choice is the material data object. In SAP Production Planning and Detailed Scheduling (PP/DS), the inclusion of a material in the planning process is primarily controlled by a single indicator, known as the “PP/DS planning indicator.” This indicator specifies whether the material should be included or excluded from the detailed scheduling processes within PP/DS.

When the PP/DS planning indicator is set, it enables the system to take the material into consideration for planning activities, such as demand planning, capacity planning, and scheduling. This simplicity in managing the planning status of materials is crucial for effective production planning, allowing planners to focus on materials that directly impact the production processes.

Other data objects like production versions, plants, and work centers may have more complex criteria for inclusion in planning processes. For instance, production versions often depend on multiple factors such as the availability of components and routing information, while plants and work centers may involve additional parameters that define their relevance to specific planning activities. Hence, they do not operate with the same straightforward approach as the material data object does in relation to the PP/DS planning indicator.
