Understanding Bill of Material Entry
A bill of material defines an item as a parent or component in the assembly. It details the specific components and quantities that are used to assemble the parent item and provides the foundation for costing and planning activities.
As you define a bill of material, you combine information from F3009, F4101, and F4102 tables. The resulting bill of material is stored in the F3002 table. Changes are stored in the F3011 table.
When you delete a parent item's bill of material, the bills of material for the item's lower level components and subassemblies are not affected.
A parent item is the end result of a bill of material. After you enter a parent item, you can define the specific components and quantities that are used to assemble the parent item. If you are working in a batch manufacturing environment, you can also define the batch quantity. The bill of material displays component information that you defined in the Item Master (P4101) and Item Branch (P41026) programs - for example, issue type code and lead time. In addition, use the Enter Bill of Material Information form to enter grade and potency information for a specific item. You can define either grade or potency information, but not both. You can enter grade or potency information only for items that are defined as lot-controlled.
To enter bills of material for the same parent item but multiple branch/plants, you can copy the original bill of material. Locate the existing bill, select Copy, and enter the new branch/plant.
Use the Enter/Change Bill program (P3002) to enter substitute items for components within the parent item, if necessary. You can use substitute items if you encounter quality issues, inventory shortages, or supplier delivery problems with the original component. To locate substitute items for any of the components, use item cross-references set up in the Item Cross Reference program (P4104).
Substitutes can also be entered by selecting a component line on the bill of material and selecting the row exit to the Bill of Material Component Substitutes program (P3002S). This substitute item will be used for the specific BOM, while the cross reference substitute is used for the item across the system.
Use production information to identify how the system issues each component from stock and how many days the component is needed before or after the start date of the work order. For each component, enter an issue code and the number of days for the leadtime offset. JD Edwards EnterpriseOne Shop Floor Management uses this production information when processing work orders.
