VB code to update existing Pivot Table

[suzetter]

I have two worksheets in the same workbook: "PIR-DT MTH" and "PIR-D
CAT"
In "PIR-DT MTH", in cell "E3" there is a string for an range value, fo
example "C4:L21"
In "PIR-DT CAT" there is a Pivot Table called "PIR1DTCAT" with Ro
Field "PIR-DTCAT" and Data Field "IR1 DT TIME" (there is no Colum
Field). The Table uses the range value mentioned above to capture th
source data for the table
The range value in "E3" on "PIR-DT MTH" changes by different triggers
the details of which are not important
However, when the value in that particular cell changes, the Pivo
Table in worksheet "PIR-DT CAT" must also update.
So I have a macro, which is supposed to capture the new range value an
update the pivot table.
I tried the very same code on a sample workbook and it works just fine
but when I test on the actual workbook, I get an error:


The call to the function is as follows:
Call Update_PivotTables("IRReports.xls", "PIR-DT MTH", "PIR-DT CAT"
"DTCAT", "1", "E3")

The actual function is as follows (note I put the values that ar
assigned to the internal variables in red for your reference):

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

Dim myexcel As Object
Dim myworkbook As Object
Dim sourceworksheet As Object
Dim objworksheet As Object
Dim PivotTableName As String
'Dim PivotRowField As String
'Dim PivotDataField As String
Dim PivotSourceData As String

Set myexcel = GetObject(, "Excel.Application") 'Point to activ
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 t
the relevant worksheet

PivotTableName = "PIR" & IRNumber & InfoType '"PIR1DTCAT"
PivotRowField = "PIR" & IRNumber & "-" & InfoType '"PIR-DTCAT"
PivotDataField = "IR" & IRNumber & " DT TIME" '"IR1 DT TIME"

If sourceworksheet.Range(RangeInfoCell).Value = "None" The
'"C4:L21"
MsgBox "You have to delete the Pivot Table"
Else
PivotSourceData = "'" & SourceWkSheetName & "'!"
sourceworksheet.Range(RangeInfoCell).Value '"PIR-DT MTH'!C4:L21"

objworksheet.PivotTables(PivotTableName).PivotTableWizar
SourceType:=xlDatabase, SourceData:= _
PivotSourceData 'THIS IS THE LINE WHERE I GET THE ERROR
ActiveWorkbook.ShowPivotTableFieldList = False
Application.CommandBars("PivotTable").Visible = False
End If

End Sub

The error which occur on the line indicated above states:
The PivotTable field name is not valid. To create a PivotTable report
you must use data that is organized as a list with labeled columns. I
you are changing the name of a PivotTable field, you must type a ne
name for the field.

I don't understand what is happening
Now all of this can be avoided, if I could only figure out how t
instead of putting the range reference like - 'PIR-DT MTH'!$C$4:$L$3
for the Pivot Table, put the value of the cell where the rang
reference string is stored - =TEXT('PIR-DT MTH'!E3
When I tried that I got an error Reference is not vali

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
