Independent Assigned Expressions
Consider this information about loading independent expressions:
• Ability to create and manage independent assigned expressions is an advanced capability subject to a separate license entitlement.
• The option set must exist in the system before you start loading independent assigned expressions.
• In the load file, include information on the independent expression immediately following information on loading the part to which it is assigned.
