You would not be able to add a node by doing a right click> add node from the admin tab the way it happend in R12.
We would follow the following procedure as the process of adding a new node to the admin tab has changed.
- Login to Service Desk/CMDB as an Administrator/ServiceDesk/CMDBAdmin,etc..
- Open the Administration Tab >Security and Role Management > Role Management >Menu Trees > On the right pane - list select "admin_tree"
- On the admin_tree Menu detail, select "File" > "Copy"
Provide a "Menu Tree Name" and "Code" and click "Save"
- Click the "Customize Menu" button.
This brings up a customizable and editable form to add nodes to, by right clicking where you want the node and entering the details.
Please contact technical support if you face any problems or have more questions on this.
