Specifying Whether to Outdate Secondary Content
The Windchill preference system (under Preference Management > Operation > CAD Data Management > Content Handling > Mark Out Of Date) lists the secondary content categories for your site. For each category of file type, setting the mark-out-of-date preference to Yes (default is No) means that upon executing various PDM operations, any secondary content of the specified category type is marked as outdated (for example, in the Attachments table on the CAD document information page). Setting the value to No means that the category does not become outdated, as it is carried forward with the CAD document.
Users can manually override conflicts caused by outdated files (for example, during a Check In attempt) by:
• Terminating Check In and manually updating the attachment, thus removing the Outdated flag.
• Removing the attachment from the CAD document.
• Resetting the status (removing the Outdated flag).
• Overriding the conflict and checking the CAD document in as is, with an Outdated status.
