Enabling Version Control for Documents
To enable version control in PTC FlexPLM, set the com.lcs.wc.document.LCSDocument.revise property to true. By default, this property is set to false.
com.lcs.wc.document.LCSDocument.revise=true
When this property attribute is set to false, document associations within the system are always made to the latest iteration of a document as a Reference document, and Described By document functionality is not available.
