Propagation
When DSNTYPE is either EXTREQ or EXTPREF, IBM Connect:Direct for z/OS will only support the propagation of the DSNTYPE, and not the DSNTYPE Version. This is because DYNALLOC (SVC 99) does not return the DSNTYPE Version information unless the “Return DSNTYPE Version information” key (DINRDSNV) is part of an SVC 99 request to create the data set.
