The Selected systems field contains a tree view of sysplexes and nested systems. It includes the systems to which the product set is to be added. To expand the branch below a sysplex click on the '+' adjacent to the sysplex.
If it contains a system to which you do not want to add the product set, select the system in this field, then click < Remove to move it back to the Eligible systems field.
You can select all systems below a sysplex by selecting the sysplex.
