Line loading in Repetitive Manufacturing (REM) is the process of assigning production quantities to specific production lines while considering their available capacity to create a feasible schedule.

The planning table (transaction MF50) is the primary tool for manual line loading. It provides a graphical interface to view planned orders, production line capacities, and their current load. Planners can manually assign or reassign planned orders to different lines to level the capacity utilization.

For an automated approach, Production Planning and Detailed Scheduling (PP/DS) heuristics for REM can be utilized. These advanced planning algorithms are designed to perform finite scheduling, meaning they consider resource capacities and material availability simultaneously to generate a feasible production plan automatically.

B. Run MRP with quota arrangement.

This method distributes requirement quantities among different sources (production lines) based on predefined quotas but does not consider capacity during the MRP run itself. Capacity leveling is a separate, subsequent step.

C. Run MRP with automatic selection of production version.

This is a source determination function that assigns all requirements to a single valid production version (line). It does not perform load distribution or capacity planning across multiple lines.

1. SAP S/4HANA 2023 Documentation - The Planning Table: "In the planning table for repetitive manufacturing

you can carry out capacity planning for your production lines... You can manually change the production quantities and dispatch them to the production lines to level the capacity at the lines." (This supports answer A).

2. SAP S/4HANA 2023 Documentation - Production Planning for Repetitive Manufacturing (PP/DS): "You can use Production Planning and Detailed Scheduling (PP/DS) to create a feasible production plan for repetitive manufacturing

taking resource and component availability into consideration... The system uses the detailed scheduling heuristic SAPREM002 to schedule the planned orders taking the available capacity of the resources into account." (This supports answer D).

3. SAP S/4HANA 2023 Documentation - Quota Arrangement: "The quota arrangement is used to determine the source of supply... It specifies which part of the total requirement of a material is to be procured from a certain source." (This confirms that quota arrangement is a quantity distribution tool

not a capacity planning function

supporting the rationale for excluding B).
