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.
The following is a sample file for loading an independent assigned expression.
<csvBeginAssignBasicIndependentExpression handler="com.ptc.windchill.option.load.Loader.beginAssignBasicIndependentExpression">

<csvname>Expression1</csvname>

<csvversion>A</csvversion>
<csviteration>1</csviteration>
