In Document management, the different versions of the same file are collected under the document number. To view previous docuemnt versions, from the docuemnt detail page, click on the Versions tab.

If a new file is uploaded with the same document number, it will be considered a new version. Unique and consistent document numbering is therefore very important within a project. You can read more about document numbers here.
​

If a Document Naming Convention is implemented for the project phase, it will act in a same way. If a document with the same document number is added, a notification is displayed, that the uploaded document will be treated as a new version of the existing document with the same document number.

By default, the latest version is downloaded, but all versions of your choice can be downloaded in the version history. The old versions can be found in the versions tab (1) of a document. Click on the download icon (2) to download the file of the specific version.

As described above, n ew versions are automatically uploaded when documents with same document number are added. New versions can also be added directly to the docuemnt by using the Add version button (3) in the document detail overview. In this upload form, only the details of this new version can be changed, the general document details such as the description, discipline and manufacturer cannot be changed.
