Attribute format restrictions

To enable you to define mapping rules, the PLM attributes and the SolidWorks attributes must have the same format or must have a conversion in order to facilitate the following matches:
Table 1. Attribute formats
From: To: String Integer Date Real
String +
Integer + + (*) + (*)
Date + + (*)
Real + + (*)

+ (*) According to regional settings.

The target attribute must be of type string if more than one attribute is mapped to this attribute. The target PLM attribute to which SolidWorks dimensions are mapped is of type string, because the value and the unit must be concatenated to a string. The target PLM attribute in a SolidWorks file-specific rule can have no other general mapping.
SolidWorks
Attributes from the SolidWorks Configuration Specific group can only be mapped to PLM item attributes. The reason is, because configuration specific attributes have different values for each configuration, these values must be mapped to the item representing a particular configuration and not to the document that describes all configurations for a particular assembly.
Relationships
You can map one SolidWorks attribute to one PLM attribute, one SolidWorks attribute to many PLM attributes, or many SolidWorks attributes to one PLM attribute.
