Plant ApplicationsAbout BOM Items
The bill of materials (BOM) is a list of formulation items required to manufacture a product. Consuming a BOM item represents the process of utilizing a BOM item within an operation. The BOM items required to complete an operation are defined in Route Editor or in the ERP system, along with details on whether consuming a BOM item is mandatory to complete the operation.
Using Unit Operations, you can perform the following tasks:
- Access a list of BOM items associated with an operation.
- View the total number of mandatory BOM items to be consumed for all the serials/lots that you have clocked on for an operation. This number appears on the BOM tab when you access an operation.
- Specify the quantity of BOM items that have been consumed for each serial/lot. If an operation requires clocking on (as defined in Route Editor or the ERP system), you can complete an operation only if all the mandatory BOM items for each serial/lot in the operation are consumed. If, however, the operation does not require clocking on, you can complete the operation even if the mandatory BOM items are not consumed.
To consume a serial/lot during production, you must perform the following steps:
- Access a BOM item to view the consumption history. You can use the consumption history of a BOM part within an operation to compare the required quantity with the consumed quantity of the BOM part.
- Consume a lot during production.
- Create a lot, in case, the BOM part does not exist.
The color of a row in the table indicates the requirement type and the consumption status of a BOM part as described in the following table.
| Color | Description |
|---|---|
| Pink | Indicates that the BOM part is mandatory to complete an operation. When you select a mandatory BOM part, the page containing the part details and consumption history displays the MANDATORY label. To complete an operation, you must consume all the mandatory BOM parts in the operation. Note: The BOM tab in the Unit Operations application displays the quantity of mandatory BOM parts required to complete an operation when the following conditions are true:
|
| White | Indicates that the BOM part is not mandatory to complete an operation. Note: These BOM parts are supplementary for an operation. |
| Blue | Indicates that consuming the BOM part is mandatory and the BOM part is consumed while executing an operation during production. Note: The BOM part row turns blue when the consumed quantity of the BOM part is greater than or equal to the lower quantity (if set), else the required quantity of the BOM parts for that operation.
