A SET SMS or SETSMS command was issued which changed the ACDS or COMMDS. Both the ACDS or COMMDS which was specified by the command and the ACDS or COMMDS previously in use are incompatible with the mode in which the system is currently running. Either they support more than eight systems and the system is running in eight name mode (in which case message IGD044I was previously issued) or they support only eight systems and the system is running in 32 name mode (in which case messages IGD064I and IGD067D were previously issued).
