Scheduled for:
The fix for this issue will be included in R1 2019, scheduled for the mid of January 2019. 

Bug can be observed in Pivot Grid => Olap Sorting example in  the most recent demo.

Sadly i do not know what this menu is called in english (and the demo cannot change language) so here is a screenshot

Set it to 'Equal' 'Lisa Cai'




If you hit ok and refresh, all values are gone.
Weirdly if you change it to not equal, you still get zero results

Bug can be reproduced in PivotGrid => Olap Support in demo application.
Under all main categories in the designer, there is a folder called "Sets" that has the exact same content.

It either is mistakingly placed under each "category" or should be something that sits on top of them in a more global fashion.

When a label filter is applied and there are repeating groups for columns and rows the GetUnderlyingData method does not return the correct items. 

Available in LIB version 2016.2.606, it will be also available in the 2016 R2 SP1 release.

It seems that the option to turn of sums has no effect for hirachie columns.
No matter if this option is checked or not, they do not disappear.

It works on regular columns.

I've been investigating a memory leak in my application and I've noticed that there are a lot of TypeBuilders and RuntimeTypes hanging around, and this number increases over time. Investigation into this shows that they are being held onto by the ModuleBuilder instance in the static instance of the Telerik PivotClassFactory.

In OLAP you are able to define ragged hierarchies. In a ragged hierarchy, the logical parent member of at least one member is not in the level immediately above the member. This can cause branches of the hierarchy to descend to different levels. RadPivotGrid doesn't show them correctly.

Available in LIB version 2015.2.914, it will be also available in the 2015 Q3.

When you apply an average aggregate function (for example via the RadPivotFieldList control) a VerificationException is thrown. The exception message is: "Operation could destabilize the runtime."

InvalidDataContractException is thrown when serializing the LocalDataSourceProvider with a DataContractSerializer and a calculation (TotalFormat) is applied.

If we apply a label GroupFilter to a RowGroupDescription/ColumnGroupDescription (through the GroupFilter property or through the RadPivotFieldList) matching groups from both the rows and columns are filtered out. 

Applying "% Difference From" total format to a calculated description formats the calculated data in RadPivotGrid as double, instead of as a percent.

Available with the R3 2016 SP1 release.

Setting the Expanded property of the GroupsExpandBehavior assigned to the RowGroupsExpandBehavior property of RadPivotGrid to True, and the RowSubTotalsPosition to None, leads to an error. 

To work this around set the RowSubTotalsPosition to Top. 

Or set the IsExpanded property of the corresponding PivotGroupHeader controls manually.

public MainWindow()
{
InitializeComponent();

// the Opacity is used to avoid the flicker that appears because the groups are rendered just before the collapse logic kicks-in.
this.pivotGrid.Opacity = 0;
this.pivotGrid.Loaded += PivotGrid_Loaded;            
}

private void PivotGrid_Loaded(object sender, RoutedEventArgs e)
{
Dispatcher.BeginInvoke(new Action(() => { 
var headers = this.pivotGrid.ChildrenOfType<PivotGroupHeader>();
foreach (var header in headers)
{
header.IsExpanded = false;
}
this.pivotGrid.Opacity = 1;
}), (DispatcherPriority)3);
}

This is the string shown in the drop down of the property descriptions shown in the RadPivotFieldList control. The option that sorts the values from Z to A is called "Classer de A à Z", but it should be "Classer de Z à A".
