+
+annotate sap.changelog.aspect @(UI.Facets: [{
+  $Type : 'UI.ReferenceFacet',

+  Target: 'changes/@UI.PresentationVariant',
+  ![@UI.PartOfPreview]
+}]);
+
+```
+
+The system now uses the SAPUI5 default setting `![@UI.PartOfPreview]: true`, such that the table will always shown when navigating to that respective Object page.
