The Content Connector attaches uploaded documents to list items based on the column-to-Keyword Type mapping configured on the content type. If a list item has a column value that matches the Keyword value on the OnBase document, the document is attached to the list item. If no match is found, then the Content Connector either does not upload the document to SharePoint, or it creates the list item to attach the document to.
The following options let you define the mappings on which matches are based and control whether the Content Connector creates new list items for documents if a matching item is not found.
