Bill of Material
Form ID: (AM208000)
You use this form to maintain the bills of material (BOMs) and production routing. The first level is the BOM summary, which represents the finished good or subassembly item to be produced. The second level is the operations level, which represents the routing of the finished item through production. The routing will include one to many operations, each one occurring in a work center. The third level is the materials, steps, tools, and overhead for each operation.
This form is used to define both production BOMs and planning BOMs (for details, see Bills of Material: Planning BOMs).
The bill of material is used to calculate the cost of item production and provides the planned cost for production orders. For more information, see Bills of Material: General Information.

Operations Table
In this table, you can view the general settings of the operation, such as a work center or processing times. If the bill of material has the On Hold status, you can remove operations, add operations, reorder operations, or modify operation settings. The operation used in the configuration cannot be deleted.
The table toolbar includes only standard buttons. For the list of standard buttons, see Table Toolbar.
Column | Description |
---|---|
Operation ID |
The numeric identifier of the operation, which determines the sequence in which the operation is executed in production orders. We recommend that you use a consistent numbering scheme that gives you the ability to insert operations, such as 10, 20, and 30 rather than 1, 2, and 3. For details, see Bills of Material: Operations. You can change this identifier, and if necessary, the system will change the sequence of operations. Any changes in the sequence will be reflected in new production orders based on this bill of material but not existing ones. Attention: When a user creates a production
order, the system generates operation identifiers, which may differ from those in the
bill of material on which the order is based. During the generation of operation IDs for
the production order, the system maintains the order of operations specified in the bill
of material. In the production order, the system assigns 0010 as the identifier
of the first operation and then increases the identifier of each new operation by 10.
Thus, the second operation ID will be 0020 and the third operation ID will be
0030.
