Subscription – Derived property value of children nodes were not flowing to target viewpoint

Summary:

When a parent node (which contains descendants) is moved from one parent to another, all its child nodes are moved along with it, as expected. After the move operation, the derived property values for the child nodes are recalculated correctly based on the property expression.

However, the system currently generates a request item only for the parent node. No request items are created for the child nodes even though their derived properties are recalculated.

Because request items are not generated for the child nodes, the updated derived property values are not propagated to the target viewpoint via subscription.

We request an enhancement to ensure that, when a parent node with descendants is moved, request items are also generated for all affected child nodes whose derived property values are recalculated, so that subscription updates flow correctly.
