Bill of Materials - Changing the Quantity of an Item

The quantity of any item can be changed in the BOM. For example, you can change the quantity of items that were added to the BOM from scratch or of parts that are modeled once but are reused throughout the design, such as bolts. When adding non-CAD items to a BOM, you must include a quantity because there is no CAD data to determine the quantity automatically. Item quantity can only be edited on the Bill of Materials tab in an item record. Only the quantities of direct children to the host item can be edited.

The BOM can only be edited when it is in the tree view. You can not edit a BOM if it is displayed in the list view. Quantities can only be edited for the direct children of the host item. To edit a quantity within a subassembly listed in the BOM, open the subassembly from the item master.

The item quantity can be either static or calculated. A calculated quantity is derived from the source CAD file and updates accordingly. A static quantity overrides the quantity specified in the linked CAD file and the original quantity contained in the CAD design is no longer reflected in the BOM.

A different font is used to identify whether a quantity is static or calculated.

Type	Font
Static	Italic
Calculated	Standard

Change the Quantity of an Item

1. In the item master, double-click an item.
2. In the item record, select the Bill of Materials tab.
3. Select a row in the BOM.
4. Click the quantity for the row.
5. Enter a number for the quantity.
6. Press Enter.

Note: When you change the quantity of an item, you override the quantity derived from the linked CAD file by default. The original quantity contained in the CAD design is no longer reflected in the BOM.

Override the Current Quantity

• Right-click the quantity and then select Static Quantity.

The quantity no longer reflects the value in the linked CAD file and does not update when the quantity is changed in the source file.

Revert the Quantity to the CAD Value

• Right-click the quantity and then select Calculated Quantity.

The quantity reflects the value in the linked CAD file.
