Hi,
Our request relates to the solution “LocalDataSourceSerialization_WPF“ on PivotGrid/Serialization/LocalDataSourceProvider in your git examples.
When we run the following scenario, we get an exception (see the attached video) :
1. Run The solution.
2. Click on “Sum of quantity” to open the menu.
3. Click on “More Calculation Options...”.
4. Choose “% Of”.
5. Choose “Date-Month” as the Base field and one of the Base Items for example “June”.
6. Press Ok.
7. Click on “Save”.
8. The system crashed with the following error (attached image).
We would be happy if you would guide us on how we could overcome the problem.
