A Requirement Source is a document that will only be referenced in a specific requirement/standard. The document will not be used or seen anywhere else in the site, except the one standard is uploaded to.
We do not recommend including links to other resources within your PDFs uploaded as Requirement Sources.
If you need to use a document for several requirements, or would like to reference page numbers of documents, you’ll need to place that document in the Document Directory tab. The page referencing function is only available in the Document Directory Sources tool.
