Alternate Structures/Formulas<br />

An item can use a product structure that is defined for a BOM code<br />

different from the item number. After you have defined a BOM code and<br />

a product structure or formula, link it to an item based on how it will be<br />

used.<br />

• If the structure/formula should be the default for an item, update the<br />

BOM code in Item Master Maintenance (1.4.1) or Item Planning<br />

Maintenance (1.4.7). The system uses this BOM code for MRP, work<br />

orders, repetitive manufacturing, and costing.<br />

• If the structure/formula should be the default for an item at a<br />

particular site, update the BOM code in Item-Site Planning<br />

Maintenance (1.4.17). The system uses this BOM code for MRP,<br />

work orders, repetitive manufacturing, and costing for an item at a<br />

site. This overrides the BOM code set up at the item level.<br />

• If the structure/formula should be available as an alternate for an item<br />

at any site, use Alternate Structure Maintenance (13.15) to link the<br />

BOM code with an item. You can then change the BOM code on a<br />

work order to this alternate structure/formula.<br />

• If the structure/formula should be available as an alternate for an item<br />

at a specific site when a specific routing is used, use Alternate<br />

Routing Maintenance (14.15.1) to link a BOM code and routing code<br />

to an item-site. You can then change the BOM code on a work order<br />

to this alternate structure/formula when using the specified routing<br />

code.<br />

Phantoms<br />

Sometimes engineering drawings and bills define transient product items<br />

that exist independently for a relatively short time and are not stocked.<br />

Instead, they are immediately consumed by higher-level products. These<br />

are called phantom structures.<br />
