The userid who is entering the option, 5 on "Sysview Essentials" must have the authorization to execute new commands under SYSVIEW.
This is defined in the INST0050 job of the SYSVIEW 17.0 SAMPJCL with the statement FAILNEWCMDS.
For example, if this userid is a SYSVIEW administrator and if the DEFAULT group is not authorized to run new commands, this should be coded in the INST0050 job:
//* Sample SYSIN input that will allow new commands for the ADMIN group and not the DEFAULT group:
//*
//* //SYSIN DD *
//* FAILNEWCMDS=NO,GROUP=ADMIN
//* FAILNEWCMDS=YES,GROUP=DEFAULT
//*
then, the SYSVIEW administrator will be able to enter the option 5 on "Sysview Essentials" menu.
