MGMTCLAS specifies the user-desired management class that is to replace the source management class as input to the ACS routines. You must have the proper RACF® authority for the management class specified. The keyword itself does not require RACF authorization.

NULLMGMTCLAS/NMC specifies that the input to the ACS routines is to be a null management class rather than the source data set’s management class.

MGMTCLAS and NULLMGMTCLAS are mutually exclusive.
