Structures
Structures are the location used to attach different variations or levels of a product. For example, you need to define variations of the product jeans. You define the variations as different levels using the Item Level Type program. Then you attach the variations that are defined at the level types with a UDC to define the structure applicable to a product.
You use the Work with Item Structures program (PCW01) to define structures. The system stores structure details in the Item Structure Detail table (FCW01).
