Message text: Only page nodes can reference existing nodes
You attempted to assign a node name that already exists in the
hierarchy. Although you are working in a mode which allows you to
reference existing nodes, this applies only to nodes that have no
dependent nodes themselves.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Choose another name or ensure (e.g. by reassigning) that the node
becomes a 'leaf' node. Then, you can reference the original node.

- Only page nodes can reference existing nodes ?The SAP error message EU167, which states "Only page nodes can reference existing nodes," typically occurs in the context of SAP's Web Dynpro or UI5 applications when there is an issue with the structure of the application’s view or component configuration. This error indicates that there is an attempt to reference a node that is not allowed in the current context, often due to incorrect hierarchy or node types.
Cause: Incorrect Node Reference: The error usually arises when a non-page node (like a context node that is not a page node) is being referenced in a way that is only valid for page nodes. Hierarchy Issues: The structure of the context nodes may not be set up correctly, leading to invalid references. Configuration Errors: There may be issues in the configuration of the Web Dynpro component or the UI5 application, where nodes are not properly defined or linked.
Solution: Check Node Types: Review the context nodes
