Note the following when building a target set.
After creating a VDG, zDP provides commands to modify the contents of the VDG so that you can adapt to your ever-growing IT needs. For example, use the MODIFY VDG command to add or remove devices from the group. Authorities for all zDP commands are managed with SAF calls. See Mainframe Enablers 10.0.0 Installation and Customization Guide for details on zDP commands which can be restricted.
