>> Can a SMF exit overwrite and change that subsystem name (or any field) in a SMF record as passed on and send these changed SMF records on to be captured by SMF subsystem and stored on a SYS1.MANx dataset later?
>Yes, we do this in IEFU83 and IEFU84 for the SYSID field. You say that you change the SYSID field, don't' you? I understood the OP's question to ask if the "SMF subsystem name" of this record can be changed. I understand that this name is not part of the SMF record passed to the exits; it is only part of the SMFEWTM macro parameter list called to initiate writing of the record.
