Revised or Saved Part to Related Document (Projects)
When a user revises a part using the Revise action or saves the part using the Save As action, the new version of the part carries forward the link to the document by default. While the Revise action always carries the link forward, you can choose to prevent the link from being carried forward during a Save As action by removing the Relationship copy rules related to this operation from wt.properties.
For example, assume the following properties are set in wt.properties:
wt.enterprise.copyRuleDelimiter=,

wt.enterprise.copyRulesN=wt.part.WTPart,Relationship,
wt.part.WTPartReferenceLink-references
The first property sets the delimiter for the copy rules to the comma (,).
The wt.enterprise.copyRulesN property is the Relationship copy rule for wt.part.WTPart. This rule copies the references forward when the type of link is WTPartReferenceLink.
If you remove the wt.enterprise.copyRulesN property, then reference links are not carried forward.
* 
As a best practice, there should be no gaps in the sequence of copy rules. If you remove a copy rule, renumber those rules that follow. For example if there are six copy rules and you remove copyRules5, then you should renumber copyRules6 so that it is copyRules5.
Duplicate numbers should never be used in the copy rules sequence.
Use the xconfmanager utility when modifying the wt.properties file. For more information on using this utility, see About the xconfmanager Utility. For more information about the properties used for copy rules, see the description of wt.enterprise.copyRules in the properties.html file.
* 
PTC recommends that you do not change the value of the wt.enterprise.copyServiceRules property. The property is used by internal services.
