The Documents Requirement functionality contains the document data requirements and associated rules for each document in the Expere Knowledge Base. A document may be chosen from navigation tree pane or from the Document drop-down menu in the top toolbar. For a static document, the Document Requirements tab will be populated with the document requirements data; for a dynamic document, the navigation tree will display the selected document, but the requirements will open either in Microsoft Office Word (or Word Pad, if Word is not installed) or in the registered PDF reader, typically Adobe Reader.
