Savable data pages in Pega cannot have a node-level scope because of potential data consistency issues in a multi-node environment. If you give access to the node level, a data integrity or data breach issue may arise. 

 Multiple Requestors: Node-level data pages are accessible by any requestor on the same node. If the data page were editable, multiple users could potentially modify the same data concurrently.

Locking Challenges: Implementing locking mechanisms to prevent conflicts in a multi-user scenario can be complex and resource-intensive. Pega avoids this overhead by restricting editability at the node level. Read-Only Suitability: Node-level data pages are typically used for storing reference data or common information that remains relatively static. Editability isn't a primary requirement for this use case.
