DOC terminates the previous subscription and then queries for data by MRN. For example, if the patients provided in Kudu are used, query for  xx2009001 and xx2009002, where: (a) xx is a wild card or empty if the system will obtain all patients with 2009001 in their MRN, or (b) if that is not possible, xx represents a company's initials for data that is available.
