Create a published version of a map
Publish creates an official copy of the document deliverable that can then be generated in any of the available formats.
Use Publish when you are ready to create a final, official version of a document: the one you intend to use for publishing in various formats and to send to localization.
Files must be assigned a version label every time they are published. The version identifies completed files for a specific release. The version label that you assign to the map is assigned, in turn, to all the files in the project. If a file is published in more than one document, it will have a label for each publication. If you want to see a file's version labels, look in the file's Properties.
