        Dim myWorkBook As Aspose.Cells.WorkbookDesigner
        Try
            Dim pivot As Aspose.Cells.Pivot.PivotTable
            Dim pchart As Aspose.Cells.Charts.Chart
            ''refreshing pivot tables and charts from all worksheets
            For Each ws As Aspose.Cells.Worksheet In myWorkBook.Workbook.Worksheets
                For Each pivot In ws.PivotTables
                    pivot.PreserveFormatting = True
                    pivot.RefreshData()
                    pivot.CalculateData()
                Next
                For Each pchart In ws.Charts

                Next
                ws.AutoFitRows(True)
            Next
        Catch ex As Exception
        End Try
        wb.Save(“C:\Reports70\temp\PIVOT_78_0.pdf”)

              Hi Amjad,

              Hi,
Thanks for providing us your template file and output PDF file.  
After an initial test, using my previous code, I found the issue as you mentioned with your template file, the percentage values in the PivotTable are wrong and not formatted correctly. I have logged a ticket with an id “CELLSNET-42145” for your issue.  We will look into your issue soon.
Once we have any update on it, we will let you know here.
Thank you.
