What determines the sequence in which materials are planned during the material requirements planning (MRP) run?

Control parameters of the MRP run, such as planning horizon or lot sizing, influence *how* the planning is executed but do not determine the hierarchical sequence based on material dependencies.

The creation date of materials is an administrative detail and has no bearing on the logical sequence of planning material requirements based on their position in the product structure.

The low-level code is a numeric identifier assigned to each material, indicating its lowest position in any product's bill of material (BOM). MRP planning processes materials starting from the highest low-level code (finished goods) down to the lowest (raw materials and components), ensuring that all components required for an assembly are planned only after the assembly itself has been addressed.

The replenishment lead time is used to calculate when orders need to be placed to meet demand, but it does not determine the processing order of materials within the BOM hierarchy during the MRP run.
