When writing quality documents, it is often necessary to link from one document to another published quality document. This is done in the editor by clicking Get link to document on the editor toolbar. A window will then appear where you can select the appropriate document from a list and confirm by clicking the Add link button.
Please note that the document being referenced does not need to have been published in order to retrieve the correct link — it only needs to have been saved in the workbook for it to appear in the selection.
If a document that has already been published contains a link to a document that is still in progress and has never been published, a message will appear stating that the document is still unpublished when the link is clicked. Otherwise, the latest version of the document will open.
