With the release of the Vault 2011 products, Vault Professional can now track change orders on any document in vault. This used to be a feature only available if you were managing an item master. It has now been extended to any document. You can simply right click any file and start a new change order from it. From there you can add any information you need including custom properties and a markup of the drawing if one is included. For a better look at this extended Vault capability, watch a short video HERE.
