Valid Syntax for TYPE Parameters
Use the internal name of the type in the TYPE parameter. The internal name can also be used in custom Info*Engine tasks and other code where there is a need to refer to a type.
You can set the internal name of a type when loading out-of-the box types or when you create (or update) a type through the Type and Attribute Management utility.
The following rules apply to the internal name:
It must be unique across all types in the system.
You are limited to 50 characters.
Only letters, numbers, periods, and underscores are supported.
Often, the internal name is the same as the type name. If you are unsure of whether a type has an internal name, you can view the information from the Type and Attribute Management utility.
* 
If the type does not have a internal name, you can add one by updating the type using the Type and Attribute Management utility. For details on accessing the Type and Attribute Manager, see the Windchill Basic Administration Guide.
