Available in LIB version 2015.2.914, it will be also available in the 2015 Q3.
If you have WriteOnly property in your Data Item and you set a collection of DataItems as ItemsSource of LocalDataSourceProvider, RadPivotGrid and RadPivotFieldList will not show any data.
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.
I would like RadPivotGrid to sort the dates defined in OLAP Cube as dates, for example: -Week 1 -Week 2 -Week 12 Instead of the current sorting: -Week 1 -Week 12 -Week 2
