The implemented is very easily: public class ExtendableLocalDataSourceFieldDescriptionsProvider : LocalDataSourceFieldDescriptionsProvider { protected override ContainerNode GetFieldDescriptionHierarchy(IEnumerable<IPivotFieldInfo> fieldInfos) { var infos = from info in fieldInfos orderby info.GetDisplayAttribute()?.GetOrder() select info; return base.GetFieldDescriptionHierarchy(fieldInfos); } We will be glad to get it out of the box for all data providers.
