Configuring Copy Over Framework for Propagating Assigned Expressions for Structure Transformation Actions
When performing structure transformation actions in the BOM Transformer or SAPSB, it is possible to configure the application to copy over assigned expressions from the upstream to downstream. For example, the actions are New Downstream Part, New Downstream Branch, Paste as New Part, Paste as New Branch, and so on.
Use the com.ptc.windchill.associativity.copyOverExpression property to control the copy over behavior of expressions from the upstream to downstream. This property is present in the associativity.properties.xconf file located at WT_HOME/codebase/com/ptc/core/foundation/associativity.
Out of the box, the following property is present in the associativity.properties.xconf file:
<Property name="com.ptc.windchill.associativity.copyOverExpression" multivalued="," default="ITEM,USAGE"/>
Consider the following key points:
com.ptc.windchill.associativity.copyOverExpression is a multivalued property. Types can be specified in a comma-separated form. For example,ITEM and USAGE.
If no value is specified in the property, then the system does not copy over any data related to the assigned expressions. That is, the system does not copy over item, usage, or occurrence expressions during the structure transformation actions.
When the USAGE type is specified in the property, the system copies over the usage as well as occurrence expressions.
