After you have created an archive file that contains the attribute definition, you need to load the archive file into the asset type definition. You do this by starting the Edit Asset Type wizard for the appropriate existing asset type, or the Add Asset Type wizard for a new custom asset type and specifying in the wizard that you are defining a new computed attribute.

For details on how to load an archive file of a computed attribute into an asset type definition, see Define Attributes for a Type.

When you have loaded the archive file, the new attribute is displayed in the list of attributes that can be assigned to an asset type profile.
