HWNDA0074E The general group cannot be added because the number of levels in the group hierarchy exceeds the maximum of five levels.
Explanation
When you added a new subcomponent for the general group, the maximum number of levels that are allowed in the hierarchy was exceeded.
Action
Review the general group hierarchy. Add the general group as a child of a group that is at a higher level in the hierarchy. Alternatively, add the general group as a top-level group.
