Low-level code

It refers to the lowest level code of the item used in BOM. The level code for not only one product but also all products is considered. As shown in the figure, for example, the low level code of Part b used at Level 1 and Level 2 is 2 in Product Z. The low level code set in this way is registered to each item, and is used to perform a level-by-level explosion.
