In the multi-level structure of a style item, the first level (style item root level 0) of an item hierarchy consists of basic details about the item. In addition to the standard JD Edwards EnterpriseOne item details, you need to specify the following details for a style item at style item root level 0: 

• Item structure.
• The size matrix grid used by the style item.
• Additional information, such as additional category codes, item model number, item number main material, and cleaning codes.
• Composition details. The composition details are important for a style item. You can specify the percentage of each material that is used in the style item.

The basic attributes of the item are inherited from the higher level (parent) to the lower level (child). 

The Style Item Master program (PCW51) acts as the entry point and the Item Structure Definition program (PCW02) acts as the exit point in the style item creation process. Based on the processing options set for the Item Master program (P4101), the forms you use to specify the general attributes of a style item root level 0 appear automatically during item creation. 

Prerequisites
The Style Item Master program acts as the entry point for the style item creation process. When you start creating style items, the Style Item Master program calls the Item Master program (P4101). The Item Master program facilitates the entry of the basic item details and integrates the style item with the standard JD Edwards EnterpriseOne items. For this reason, you need to set up the Item Master program before you start creating a style item. You must also set up the Additional Style Item Information, Composition, and Structure Definition processing options on the Style tab of the Item Master program to display the following forms when you enter item details during style item creation: 

• Additional Style Item Information (WCW45A) to specify supplemental category codes and cleaning codes that are applicable for the style item.
• Work With Composition (WCW44A) to define the materials used in the manufacture of the style item and their respective percentages of the composition.
• Item Structure Definition (WCW02B) to view and create the child level item definitions. If the processing option of the Style Item Master program is set up for the manual creation of items, then you must use the Item Structure Definition form to create the item hierarchy and the end-level items.
