How to Specify whether the PivotTable is compatible for Excel2003 while refreshing PivotTable

The following sample code explains the usage of PivotTable.is_excel_2003_compatible property. The original string is 383 characters long. But when PivotTable.is_excel_2003_compatible property is set true and pivot table is refreshed, the data of cell B5 of the pivot table is truncated and it becomes 255 characters long. However, when PivotTable.is_excel_2003_compatible property is set false and pivot table is again refreshed, the data of cell B5 of the pivot table is not truncated and remains 383 characters long. Please read the comments inside the code for better understanding of this property.
