VB code to update existing Pivot Table

Hi Suzetter

Two things to try. First, with your existing set up make sure that all of
the fields in your source table have headings. That error usually means
there is a missing header. Maybe it got over written. That should fix it

Second: You can use a named range as the source of your pivot table like this

ActiveWorkbook.PivotCaches.Add(SourceType:=xlDatabase, SourceData:="test"). _
CreatePivotTable TableDestination:="", TableName:="PivotTable3"

Where "test" is a named range. Then you can write code to assign that name
to whatever range is appropriate. Something like

activecell.currentregion.name = "test"


Refresh your table and you're good to go
ActiveSheet.PivotTables("PivotTable3").RefreshTable

regards,
Mike

Believe it or not, I was trying the suggestion about the named range in the meantime, but I have run into other problems:

I have 2 worksheets in the same workbook
On worksheet "PIR-DT MTH" there is a cell (i.e. "E3") which contains a string value representing a range of cells, eg. "C4:L32"
This range value changes due to specific triggers which aren't important
In "PIR-DT MTH", there is a named range called "PIR1DB" with the same cell range that is stored in the cell "E3"
On the other worksheet "PIR-DT CAT", there is a pivot table "PIR1DTCAT" which has it's data range defined as the named range "PIR1DB" on the previous worksheet
So, the jist of the idea is that when the content in cell "E3" on "PIR-DT MTH" changes, I update the range that the workbook Name "PIR1DB" refers to
When the named range is updated, the pivot table "PIR1DTCAT" will be refreshed to show data for the changed range
I've toiled over this code over and over and over and all the variables show the correct values (using the VB Debug window)
But for some strange reason, the line which is supposed to set a new range to the Name doesn't work at all

The call to the function looks like this:
Call Update_PivotTables("IRReports.xls", "PIR-DT MTH", "PIR-DT CAT", "DTCAT", "1", "E3")

The actual function looks like this (I have placed the actual values in comments at the end of the line so you can follow what is happening):

Public Sub Update_PivotTables(WkBook As String, SourceWkSheetName As String, _
ObjWkSheetName As String, InfoType As String, _
IRNumber As String, RangeInfoCell As String)

Dim myexcel As Object
Dim myworkbook As Object
Dim sourceworksheet As Object
Dim objworksheet As Object
Dim PivotTableName As String
Dim PivotSourceData As String
Dim NameRef As String

Set myexcel = GetObject(, "Excel.Application") 'Point to active excel application
Set myworkbook = Excel.Application.Workbooks("IRReports.xls") 'Point to the relevant workbook
Set sourceworksheet = myworkbook.Worksheets(SourceWkSheetName) 'Point to the relevant worksheet
Set objworksheet = myworkbook.Worksheets(ObjWkSheetName) 'Point to the relevant worksheet

PivotTableName = "PIR" & IRNumber & InfoType ' PIR1DTCAT

If sourceworksheet.Range(RangeInfoCell).Value = "None" Then ' C4:L33
'There is no downtime data, hence the pivot table will not be updated
Else
PivotSourceData = "='" & sourceworksheet.Name & "'!" & sourceworksheet.Range(RangeInfoCell).Value ' 'PIR-DT MTH'!C4:L33
NameRef = "PIR" & IRNumber & "DB" ' PIR1DB
myworkbook.Names.Add NameRef, PivotSourceData 'This is the line which doesn't work
objworksheet.PivotTables(PivotTableName).PivotCache.Refresh

myworkbook.ShowPivotTableFieldList = False
Application.CommandBars("PivotTable").Visible = False
End If

End Sub

Changing the Named range doesn't work
The source variable (i.e PivotSourceData) would have the correct information in but and after the line is executed and you check the source range for PIR1DB is says something completely different like "='PIR-DT MTH'!BJ9:BS38"
I have no clue where it gets this from
And everytime you run the code, the strange range changes
Even when I hardcode the value (see below) , it still doesn't work
myworkbook.Names.Add "PIR1DB", "='PIR-DT MTH'!C4:L33"

This is just weird, the fact that hardcoding the values doesn't work means something is drastically wrong somwhere
Am I using any predefined VB words?
Is the sky falling?

And yes all my columns have headings etc. This Excel is possessed, I know it :-)
