Independent Assigned Expressions
Consider this information about loading independent expressions:
Creating and managing of independent expressions is available only to members of the Platform Structures group.
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.
