Product-Related Master Data 
After you set up your shop floor-related master data, you define your product-related master data to tell the system the details about what you manufacture on your shop floor. You use this information when you release a shop order to the floor to build a certain quantity of the product.
When you set up your product-related master data, you must decide:
Which products that you manufacture, and which components that you manufacture or purchase to build your products, you want to track in the system (see Genealogy)
What information you want to collect about components (see Assembly Data Type)
Which bills of material (BOMs) you use to manufacture your products (see Bill of Material (BOM))
Whether you use kitting (see Kit)
