Attention program . . . . . . . . . . . . :
That’s the attention key program, not the system request menu.
You could try restricting the authority on the QMNSYSRQ program by revoking the end users access (even easier if they all belong to a group profile).
It was the System Request Menu, QGMNSYSR. After I submitted my question I found what we really wanted was to secure the ability to Transfer to a Second Job. We were having an issue with record locks.
Anyway, I revoked authority to the command TFRSECJOB for *Public and then granted authority to the command to the QPGMR Group.
This appears to have solved my problem.
Thank You for the assistance,
