Hi Durai,
thanks for fast response and for providing the example.
I could now reproduce the error also with your provided project. All I did was adding another PivotComputationInfo.
For that I added the property "NetAmount" to the model and added it like this to the xaml:
<syncfusion:PivotGridControl.PivotCalculations>
<syncfusion:PivotComputationInfo CalculationName = "Total" Description = "Summation of values" FieldName = "Amount" Format = "C" SummaryType="DoubleTotalSum"/>
<syncfusion:PivotComputationInfo CalculationName = "Total" Description = "Summation of values" FieldName = "Quantity" Format = "#,##0"/>
<syncfusion:PivotComputationInfo CalculationName = "Total" Description = "Summation of values" FieldName = "NetAmount" Format = "C" SummaryType="DoubleTotalSum"/>
</syncfusion:PivotGridControl.PivotCalculations>
So it looks like with two columns everything works fine. But when using more columns the last column is not added to the PDF (only for the last group - in this example United States).
