changetracking Variable
Change tracking markup is output based on the setting of the changetracking parameter in the PTC Arbortext Generator pipeline filter (Arbortext-path/composer/epicGenerator.ent). The changetracking parameter accepts the following values:
nothighlighted — Outputs the view of the document specified by the set viewchangetracking command. However, if set viewchangetracking is set to changeshighlighted, then nothighlighted outputs the changes applied view of the document. This is the default setting.
original — Outputs the original view of the document.
changesapplied — Outputs the changes applied view of the document.
changeshighlighted — Outputs the changes highlighted view of the document.
active — Outputs the view of the document specified by the set viewchangetracking option
