Materials may appear in several products and in several production levels of a product. The low-level code represents the lowest level of usage of a material within all product structures.

It determines the sequence in which the materials are planned. The system plans materials with the low-level code 0 first and then those with 1 and so on. The lower the low-level code is, the higher the number assigned to the level.

You have created BOMs for the materials that you want to plan.

The low-level code is stored in the BOM management program in the material master (Additional data, ) and is entered in the planning file.
