In SAP S/4HANA PP/DS, theFinite Scheduling with Reversestrategy (configured in the strategy profile, transaction /SAPAPO/CDPSC11) schedules operations backward from a fixed end date, respecting finite capacity. To allow scheduling in the past (e.g., before today’s date):

Specify a negative offset time(A): In the strategy profile (Detailed Scheduling tab, field: Scheduling Offset), a negative value (e.g., -2 days) shifts the scheduling reference point into the past. This allows operations to be scheduled before the current date, accommodating scenarios where late planning or historical adjustments are needed, while still respecting capacity constraints.

Negative opening period(B) isn’t a standard PP/DS parameter—it’s a production order term (MRP 2 view) for order start buffers, not scheduling control.Negative planning horizon(C) (Planning Horizon in /SAPAPO/CDPSC11) defines the future planning scope, not past scheduling.Negative PP/DS horizon(D) refers to the PP/DS planning horizon (Customizing), which limits planning scope forward, not backward. This is per SAP’s PP/DS scheduling configuration.

Thelow-level codein SAP S/4HANA (visible in MD04 or calculated during MRP) indicates the deepest level at which a material appears in any BOM across all products, starting from 000 (finished goods) downward. Its key features are:

To determine how costs are rolled up by product costing(B): In Product Costing (CO-PC), the low-level code ensures costs are calculated bottom-up, starting with the lowest-level components (e.g., raw materials) and rolling up through assemblies to the finished product (transaction CK11N). This guarantees accurate cost aggregation.

To determine the sequence in which materials are planned in MRP(C): During MRP (MD01/MD02), the system plans materials in ascending order of low-level codes (lowest first), ensuring dependent requirements for lower-level components are calculated before higher-level assemblies, avoiding planning gaps.

Priority of alternative components in ATP(A) is managed by BOM alternative item strategies (e.g., 100% check), not low-level codes.Use of sub-items in BOM(D) is defined by item categories (e.g., "R"), not influenced by low-level codes. This is per SAP’s planning and costing logic.

In SAP S/4HANA, the duration of an operation in production (e.g., for scheduling production orders) is determined by data maintained in:

Work center(A): The work center (transaction CR01/CR02, Capacity tab) contains capacity data and formulas (e.g., Setup Formula, Processing Formula) that calculate operation times based on machine or labor availability. The "Standard Value Key" (Basic Data tab) defines which time elements (e.g., setup, processing) are relevant, influencing duration.

Routing(C): The routing (transaction CA01/CA02) specifies operation details, including standard values (e.g., setup time, machine time) entered for each operation. These values, combined with work center formulas, determine the exact duration of the operation during scheduling (e.g., lead time scheduling in CO01).

Material master(B) provides in-house production time (MRP 2 view), but this is a high-level estimate for the entire material, not operation-specific.Production version(D) links BOMs and routings but does not directly store operation duration data—it references the routing. This is per SAP’s production planning master data structure.

In SAP S/4HANA, during the creation of planned orders or production orders, the system relies on specific master data to determine the production process, components, and operations. The system checks the following:

In the bill of material (BOM)(C): The BOM (maintained in transaction CS01/CS02) defines the components required for production. MRP explodes the BOM to generate dependent requirements for planned orders, and production orders inherit this structure. The BOM’s validity (e.g., date, lot size) and usage (e.g., production) are verified during order creation.

In the MRP controller(D): The MRP controller (material master, MRP 1 view, field: MRP Controller) influences master data selection indirectly through its configuration in Customizing (e.g., Production > Material Requirements Planning > Master Data > Define MRP Controllers). It can determine planning parameters and production versions, affecting order creation.

In the routing(E): The routing (maintained in transaction CA01/CA02) specifies the operations, sequence, and work centers for production. During order creation, the system selects the routing to define the production process, ensuring the correct operations are assigned to the order.

In the production version(A) is critical for linking BOMs and routings, but the system checks within the BOM and routing directly once the version is selected, not the version itself as a "check location."In the work centers(B) provides capacity and scheduling data, but the system does not check master data selection settings there—it uses the routing to reference work centers. This aligns with SAP’s production planning master data integration.
