Weird behaviour of VBA when generating multiple PivotCharts

[deltaquattro]

Hi guys,

I'm really in a pinch this time. It's Friday evening and I cannot
understand why VBA is complaining about this piece of code: the goal
is to build multiple PivotTables and associated PivotChart

Sub CreatePivotCharts(SheetName As String)
'Creates multiple PivotTables and PivotCharts associated with the data
stored in
'sheet SheetName
Dim PTCache As PivotCache
Dim PT As PivotTable
Dim SummarySheet As Worksheet
Dim I As Long, Row As Long
Dim NumTables As Long, Index As Long
Dim ItemName As String, IsEmbedded As Boolean

'All PivotTables are stored in a single sheet, called PivotTables
'Delete PivotTables sheet if exists
On Error Resume Next
Application.DisplayAlerts = False
Sheets("PivotTables").Delete
On Error GoTo 0

' Create PivotTables sheet
Set SummarySheet = Worksheets.Add
SummarySheet.name = "PivotTables"
SummarySheet.Move after:=Worksheets(Worksheets.count)

'Create Pivot Cache
Set PTCache = ActiveWorkbook.PivotCaches.Add(SourceType:=xlDatabase, _
SourceData:=Sheets(SheetName).Range("A1").CurrentRegion.Address)

' Create Pivot Tables and PivotCharts
NumTables = NumProperties - 2 ' NumProperties is a global variable,
and the 'number of PivotTables to be written is equal to NumProperties
-2
Row = 1
For I = 1 To NumTables
Index = I + 2
Set PT = Sheets("PivotTables").PivotTables.Add( _
PivotCache:=PTCache, _
TableDestination:=SummarySheet.Cells(Row, 1))

'Add fields
With PT

'Rows
ItemName = Sheets(SheetName).Cells(1, 1)
.PivotFields(ItemName).Orientation = xlRowField

'Columns
ItemName = Sheets(SheetName).Cells(1, 2)
.PivotFields(ItemName).Orientation = xlColumnField

'Data
ItemName = Sheets(SheetName).Cells(1, Index)
With .PivotFields(ItemName)
.Orientation = xlDataField
' .Function = xlSum
End With

End With

' Create associated PivotChart
Call CreatePivotChart(ItemName, PT)

Row = Row + PT.TableRange1.Rows.count + 5 ' 5 rows of space
between each
' PivotTable

Next I
End Sub
--------------------------------------------------------------------------------
Sub CreatePivotChart(ChartName As String, PT As PivotTable)
' Create a PivotChart associated with PivotTable PT
Dim cht As Chart

'Delete PivotChart sheet if exists
On Error Resume Next
Application.DisplayAlerts = False
Sheets(ChartName).Delete
On Error GoTo 0

' Add PivotChart sheet
Set cht = Charts.Add
cht.Move after:=Sheets(Sheets.count)
'MsgBox PT.TableRange1.Cells(1,1).Value

With cht
.name = ChartName
.SetSourceData Source:=PT.TableRange1 ' that's the line where the
code stops

'Change format
.ChartType = xlLineMarkers

End With

End Sub
--------------------------------------------------------------------------------

When I run the code, the first iteration of the For cycle in
CreatePivotCharts (the first subroutine) works fine, so the first
PivotTable and associated PivotChart are created all right. However,
at the second iteration, the code stops at the line indicated above
in subroutine CreatePivotChart (the second subroutine, yes I know I've
got a great fantasy for names
The following runtime error is given:

Run-time error '1004':
The source data of a PivotChart report cannot be changed. You can
change the view of data in a PivotChart report by reorganizing its
fields or items, or by changing its associated PivotTable report.

and, choosing the option "Debug", I can see that the PivotTable
presently selected in the sheet "PivotTables" is the first one, not
the second!! However, if I uncomment the line

MsgBox PT.TableRange1.Cells(1,1).Value

in the sub CreatePivotChart, I can see that at the second iteration PT
is pointing to the second PivotTable!! How's that possible? Can you
please help me? Will I pass the w/end in the office trying to solve
this? Thanks in advance,

Best Regards
