Diagnosis
After the enhancement of a UIcomponent, the page of the view is automatically copied to thecustomer namespace. Therefore, after importing a Support Package orperforming an upgrade, changes in the SAP standard view page of the UIcomponent are not transferred to the enhanced view page.
The original SAP view contains context node &V1&, which is missing in apage attribute of enhanced view.

Procedure
Check the context node and page attribute of view enhancement andcomplete them manually. Otherwise, if a configuration based on thecontext node exists for a view, it cannot be loaded correctly at runtimeor exceptions occur.
