When Updating Documents with Addendum's, you will want to first create a sub-folder ( See Creating Folders ) so that you can locate a shadow copy in a specific place relating to the revision / update. This makes it easier for people to locate specific items.
Place a check next to the documents you would like to revise
Click the Revise Icon the following screen comes up
You can change the Status ( Addendum ), Issue and Document Date. Browse to the updated file and save
** Note** From the drop down, select the folder you setup for this revision and a second / reference copy will be placed in that folder.
