The Advanced Planning flag is a field that indicates whether a data object is relevant for planning with Production Planning and Detailed Scheduling (PP/DS) in SAP S/4HANA. PP/DS is a component of Advanced Planning that provides more precise and flexible planning capabilities for critical products and resources. You can set the Advanced Planning flag for the following data objects:

Work Center: This is a master data object that represents a location where operations are performed. A work center can have different capacities, such as machine, labor, or power, that are used for scheduling and capacity planning. You can set the Advanced Planning flag for a work center to enable it for PP/DS planning. This means that the work center can be used as a resource in PP/DS and its capacity can be optimized by PP/DS heuristics or optimization tools.

Material: This is a master data object that represents a product or a component that is produced, procured, or consumed in a business process. A material can have different views, such as basic data, MRP, sales, or production, that contain different attributes and parameters for planning and execution. You can set the Advanced Planning flag for a material to enable it for PP/DS planning. This means that the material can be planned with exact times and quantities in PP/DS and its availability can be checked by PP/DS pegging.

The production version (B) and the plant (D) are not data objects that can have the Advanced Planning flag. The production version is a master data object that defines the combination of a bill of material (BOM) and a routing or a production process model (PPM) for a material. The production version does not have a separate flag for PP/DS, but it inherits the flag from the material and the work center. The plant is an organizational unit that represents a physical location where materials are produced or stored. The plant does not have a flag for PP/DS, but it is assigned to a location in PP/DS that represents the geographical or logical grouping of plants for planning purposes. References:https://blogs.sap.com/2018/02/12/ppds-for-sap-s4hana-advanced-planning-a-powerful-planning-and-scheduling-tool/
