Question:

When does the version number of a document change in Vault PromoMats and Medical?

Answer:

A document version number (example: 1.3) is a standard field composed of the major version (1.0) and the minor version (0.3).

1. The Minor version increases every time a new version of the document is uploaded, when a Draft is created, or when the document is checked out and checked in.
   
   
   
   
2. The Major version changes once a document reaches the Steady State (such as Approved). The latest minor version becomes a major version (e.g., 0.3 becomes 1.0).
