Multi-level BOM import from CAD software into MRP system

BOM is a list of parts that are needed to produce a product or an assembly. If the BOM lists only the details of which the product is directly composed, then this is a one-level BOM. If a part is produced inside the company, then it will have its own BOM. If the BOM of the final product includes the BOMs of its components, it is a multi-level BOM.
