An attachment is a supplemental file, e.g., a text document, that is attached to an application case. The agency can attach scanned documents that provide information in support of an application case such as a birth certificate or bank statement. A range of file types are supported including Microsoft® Word, Microsoft® Excel and PDF. The system does not restrict the file size of the attachment although the agency may wish to set a limit using an environment variable. Once the file is attached to the application case, it may be accessed by other system users who have appropriate security privileges.
