Bulk Items Overview
* 
This topic only applies to objects authored in Creo Parametric. Additionally, the functionality is only available in Windchill PDMLink or Windchill ProjectLink.
Bulk items represent CAD parts that do not require solid models but must be represented in the Bill of Materials (BOM) or in PDM systems. (items such as paint or sealant). They can also be items such as fasteners that are used in multiple places in an assembly.
For example, a parameter defined in Creo Parametric, BOM_REPORT_QUANTITY, contains quantity and unit parameters, used to describe the quantity and unit of quantity for a bulk item (if no unit is explicitly assigned and the quantity is an integer value, the system assumes the unit to be "each". If the quantity is a real value, the unit is “As Needed.”). This information is passed toWindchill upon upload (either on the EPMDocument Master or on the EPMMemberLink) and can be displayed in tables showing the WindchillQuantity column.
The following information describes the characteristics of bulk item display in Windchill:
• In the PIM (Product Information Manager), when you create a part with Described By links to CAD documents, you are only able to map a bulk item to a part with the same units.
• When you display theStructure tab for a parent of a bulk item, then the Quantity value displays the user-defined quantity (with any units) defined in the CAD application.
• When using the part for the bulk item in a product structure, the Quantity for the part matches the value specified for this component in its assembly.
• Once the unit for a bulk item parameter is assigned, the unit can only be modified to another unit of the same measurement type. For example, if a length unit is assigned, it can only be modified to another unit of length, not area or volume.
