VTAM® issues this message in response to a DISPLAY ID command for a host cross-domain resource manager. This message indicates whether the named host will process session initialization requests from cross-domain resources that are not explicitly defined to the host. If you specified CDRDYN=YES on the host CDRM definition statement, the host will support sessions for dynamically defined resources.

A value of YES in this message combined with a value of OPT in message IST389I means that VTAM will build a dynamic CDRSC entry if necessary.
