How can you limit the validity of a bill of material (BOM)?

You can limit the validity of a BOM by plant and by period. The plant determines the organizational area of validity for the BOM, and you can assign the same BOM to different or further plants if the prerequisites are met. The period of validity for a BOM is restricted by the valid-from date and the valid-to date in the BOM header and item, which determine when the BOM becomes effective and when it ends. References: Validity of Bills of Material, BOM Item Validity
