Which system is indicated as the source for parts and BOM data for CAPP?

• A. ERP
• B. PDM
• C. PLM
• D. MES

Answer: (B)

Parts and BOM data used in process planning (CAPP) come from the PDM system because it is designed to manage engineering data, including the structure of the product and the bill of materials, with proper revision control linked to CAD models. This makes PDM the authoritative source for the EBOM—engineering BOMs and the associated part attributes that planners rely on to define manufacturing steps, routing, and operations. While ERP can provide BOMs for production scheduling and procurement and MES handles shop-floor execution, the data that feeds CAPP most directly originates in PDM, which keeps design intent, part numbers, and relationships up to date for accurate process planning. PLM can influence BOM information as well, but PDM is the system most closely aligned with managing the parts and BOM data used by CAPP.
