By default, only Documents that the Expert System knows are required, or documents that a user has chosen as relevant, are shown in worksheet tables. To show all candidate Compliance Documents disable the filter shown.
You can then assert that one or more candidate documents is in fact relevant for provision of supporting evidence - in which case document compliance will only be considered to be fully met for the credit if a file Attachment is provided for each relevant document also (in addition to any required documents).
Use the ATTACH! link to upload a file Attachment to the Document via its edit page, optionally entering a page range or section range to indicate where the supporting evidence may be found, then to return to the worksheet.
