Remove rows from the BOM that are no longer needed.
For example, you might need to remove individual parts because you track and buy the assembly as a single item.
Items listed in the BOM can be removed by deleting the rows containing the items. When a row is removed from the BOM, the link to the item and links to all children of the item are removed. Removing a row for an assembly in the BOM removes the assembly row and all corresponding child rows.
In the item master, double-click an item.
In the item record, select the Bill of Materials tab.
Click Edit on the toolbar to put the item record in edit mode.
Right-click on a row in the BOM and select Remove Row.
The link to the item and links to all children of the item are removed.
