Before SMS-managed data sets are expired, a check is made to ensure that the data set has a backup copy. Some sites want to override the requirement that SMS-managed data sets have a backup copy before they are expired. The following patch provides this capability:

PATCH .MCVT.+431 BITS(......1.)    /* Override the requirement    */
                                   /* that SMS-managed data sets  */
                                   /* have a backup copy before   */
                                   /* they can be expired         */
