When APPC/MVS inbound conversations create work scheduled by the APPC/MVS transaction scheduler, SMF writes a type 33 subtype 1 record. When an APPC/MVS inbound or outbound conversation is deallocated, SMF writes a type 33 subtype 2 record. See APPC/MVS Accounting for more detailed information about APPC/MVS accounting.
The subtype is indicated in the SMF33TYP field. For information on subtype selectivity, see SYS and SUBSYS with TYPE and NOTYPE — Selecting subtypes for SMF recording.
