I am trying to change Pivot table {Function} property to specify it is xlCount or xlAverage or xlSum etc. But I got the error msg below:

==========

Unable to set the Function property of the PivotField class

Win32::OLE(0.1711) error 0x80020009: "Exception occurred" in PROPERTYPUT "Function" at WeeklyRpt.pl line 138

Here is the code. I am using Win32::OLE.

use strict;
use Math::BigInt;
use Cwd;
use Time::Local;
use POSIX qw(strftime);

use Win32::OLE::Const 'Microsoft Excel'; # use OLE/Excel
$Win32::OLE::Warn = 3; # die on errors...

<<<...snip...>>>

# Create worksheet after cases data sheet
$act_sheet = $workbook->Worksheets->Add({After=>$ws_data}) or die Win3
+2::OLE->LastError();
#Get current active sheet name
$act_sheet_name = $workbook->ActiveSheet->{Name};    #Get current acti
+ve sheet name
$act_sheet = $workbook -> Worksheets( "$act_sheet_name" );
$act_sheet->{name} = 'ClosedRegion';    #Change sheet name http://www.

$pv_table = $ws_data->PivotTableWizard( { SourceType=>xlDatabase, Sour
+ceData=>$data_rang,
                        TableDestination=>'ClosedRegion!R3C1', TableNa
+me=>"PivotTable2"} );

$pv_table->AddFields( "Owner Region" );
$pv_table->PivotFields("Owner Region")->{Orientation} = xlDataField;
$pv_table->PivotFields("Owner Region")->{Function} = xlCount;

The last line code causes the problem. I have also ever tried

$pv_table->PivotFields("Owner Region")->SetProperty("Function",xlCount);

but does not work out either.

Could you help out?

Thank you!
