File Format for Importing Parts
The following table describes the format of data in a part import spreadsheet. It defines the column header, whether the column is required, and the description of the data that can be entered for each column.
* 
In a spreadsheet, all discrete values (a value that must be one of few fixed values) must be entered as an internal value, not the display value. For example, for the Default Unit attribute, use as_needed (internal), not As Needed (display).
Column Header
Required
Editable on reimport

• vendor parts: com.ptc.windchill.suma.part.VendorPart

The class types can be defined in the logical identifiers file with an alias. For example, wt.part.WTPART=part. Part, Manufacturer Part, and Vendor part are included in the logical id file.
