Assume that you deploy a BizTalk application that contains a map file to a BizTalk group on a computer that is running Microsoft BizTalk Server. When you click the Maps folder, you receive an error message that resembles the following:
Schema referenced by Map 'map_name’ has been deleted. The local, cached version of the BizTalk Server group configuration is out of date. You must refresh the BizTalk Server group configuration before making further changes.
