Production BOM
The Production BOM Lines in Dynamics 365 Business Central are extended with three new fields when the Manufacturing Variances Management app is enabled. These fields allow users to define and manage variance policies and tolerances for individual materials within a Bill of Materials (BOM).
| Field Name | Description |
|---|---|
| Variance Policy | Choose one of the following options: Warning: Specifies that the system will show a warning to alert the user when setting values outside the specified tolerances. Block: This option does not allow the user to consume or produce above or below the specified tolerances. None: Means no variance check is done. (however, the variance is recorded) Default: Means that the policy defined on company level is used for this item. This value is defaulted from the item or SKU card. |
| Under Consumption Tolerance (%) | Specifies the under-output tolerance in percentage for the selected item. This value is defaulted from the item or SKU card. |
| Over Consumption Tolerance (%) | Specifies the over output tolerance in percentage for the selected item. This value is defaulted from the item or SKU card. |
