When you edit an item, Dimensions CM creates a new revision of the item and updates the revision ID according to your process model rules. For example, in the following figure, the process model rules determine that Revision 2 is automatically increased to Revision 3.
When you check out an item, the new revision is reserved in Dimensions CM. After you modify the revision in your work area, you check it in.
You can also modify an item by revising it from a file in your work area, without first checking out the item. Dimensions CM creates a new revision of the item from the contents of the file, and the item revision ID is updated according to your process model rules. In the web client, you can use the Deliver command to do this. In the case of a stream, you do not modify items individually in the repository. You modify items in the stream by modifying the files in the work area and then performing a deliver of the changes.
