What identifies whether a specific record is classified as a BOM or material?

The construction type field is critical in differentiating whether a specific record is classified as a Bill of Materials (BOM) or a material in SAP S/4HANA. This field specifies how the BOM is structured and how it relates to individual component materials. For instance, certain construction types are indicative of different BOM purposes, such as production, engineering, or sales, each defining how the components in the BOM are organized and used within the broader manufacturing and planning processes.

Other fields, such as the material category, the product line field, and the type of goods field, do play roles in the overall classification and management of materials and products in the system, but they do not provide the same level of specificity regarding the structural classification of records as the construction type field does. The construction type field directly informs the system and users about the nature of the record, making it fundamental for identifying BOMs and associated materials.
