According to the family table
The document under test is a part or assembly. 
Perform the operation according to the family table.
Configurations—which control the various shapes or states of parts and assemblies—can be managed by a part family. This part family is typically defined by an Excel table that can either be embedded in the SOLIDWORKS file or linked to an external file. The drop-down list therefore allows you to process the SOLIDWORKS document based on this Excel table.
