How to create pivot table using vba - excel

Question

I am newbie in vba and am trying to create a PivotTable using VBA with excel.
I would like to creat like as below image as input sheet.
I am trying to add row labels of region, month, number, status and values are value1, value2 and total here I am able to set range for pivot, while executing it creates "pivottable" sheet only. not generate any pivot table for sheet1.
My Code:
Option Explicit
Public Sub Input_File__1()
ThisWorkbook.Sheets(1).TextBox1.Text = Application.GetOpenFilename()
End Sub
'======================================================================
Public Sub Output_File_1()
Dim get_fldr, item As String
Dim fldr As FileDialog
Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
With fldr
.AllowMultiSelect = False
If .Show <> -1 Then GoTo nextcode:
item = .SelectedItems(1)
If Right(item, 1) <> "\" Then
item = item & "\"
End If
End With
nextcode:
get_fldr = item
Set fldr = Nothing
ThisWorkbook.Worksheets(1).TextBox2.Text = get_fldr
End Sub
'======================================================================
Public Sub Process_start()
Dim Raw_Data_1, Output As String
Dim Raw_data, Start_Time As String
Dim PSheet As Worksheet
Dim DSheet As Worksheet
Dim PCache As PivotCache
Dim PTable As PivotTable
Dim PRange As Range
Dim LastRow As Long
Dim LastCol As Long
Start_Time = Time()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Raw_Data_1 = ThisWorkbook.Sheets(1).TextBox1.Text
Output = ThisWorkbook.Sheets(1).TextBox2.Text
Workbooks.Open Raw_Data_1: Set Raw_data = ActiveWorkbook
Raw_data.Sheets("Sheet1").Activate
On Error Resume Next
'Worksheets("Sheet1").Delete
Sheets.Add before:=ActiveSheet
ActiveSheet.Name = "Pivottable"
Application.DisplayAlerts = True
Set PSheet = Worksheets("Pivottable")
Set DSheet = Worksheets("Sheet1")
LastRow = DSheet.Cells(Rows.Count, 1).End(xlUp).Row
LastCol = DSheet.Cells(1, Columns.Count).End(xlToLeft).coloumn
Set PRange = DSheet.Range("A1").CurrentRegion
Set PCache = ActiveWorkbook.PivotCaches.Create_(SourceType:=xlDatabase, SourceData:=PRange)
Set PTable = PCache.CreatePivotTable(TableDestination:=PSheet.Cells(1, 1), TableName:="PRIMEPivotTable")
With PTable.PivotFields("Region")
.Orientation = xlRowField
.Position = 1
End With

Answer 1

This needs some tidying up but should get you started.
Note the use of Option Explicit so variables have to be declared.
Columns names are as per your supplied workbook.
Option Explicit
Sub test()
Dim PSheet As Worksheet
Dim DSheet As Worksheet
Dim LastRow As Long
Dim LastCol As Long
Dim PRange As Range
Dim PCache As PivotCache
Dim PTable As PivotTable
Sheets.Add
ActiveSheet.Name = "Pivottable"
Set PSheet = Worksheets("Pivottable")
Set DSheet = Worksheets("Sheet1")
LastRow = DSheet.Cells(Rows.Count, 1).End(xlUp).Row
LastCol = DSheet.Cells(1, Columns.Count).End(xlToLeft).Column
Set PRange = DSheet.Range("A1").CurrentRegion
Set PCache = ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:=PRange)
Set PTable = PCache.CreatePivotTable(TableDestination:=PSheet.Cells(1, 1), TableName:="PRIMEPivotTable")
With PTable.PivotFields("Region")
.Orientation = xlRowField
.Position = 1
End With
With PTable.PivotFields("Channel")
.Orientation = xlRowField
.Position = 2
End With
With PTable.PivotFields("AW code")
.Orientation = xlRowField
.Position = 3
End With
PTable.AddDataField PSheet.PivotTables _
("PRIMEPivotTable").PivotFields("Bk"), "Sum of Bk", xlSum
PTable.AddDataField PSheet.PivotTables _
("PRIMEPivotTable").PivotFields("DY"), "Sum of DY", xlSum
PTable.AddDataField PSheet.PivotTables _
("PRIMEPivotTable").PivotFields("TOTal"), "Sum of TOTal", xlSum
End Sub

Answer 2

The code in my answer below is a little long, but it should deliver you the result you are seeking for.
First, to be on the safe side, first check if "Pivottable" sheet already exists in Raw_data workbook object (no need to create it again).
Second, the code is divided in the middle to 2 sections:
If the MACRO was ran before (this is the 2+ times you are running it), then "PRIMEPivotTable" Pivot-Table is already created, and there’s no need to create it again, or to set-up the Pivot-Table’s fields.
All you need to do is refresh the PivotTable with the updated PivotCache (with updated Pivot-Cache’s source range).
If this is the first time running this MACRO, then you need to set-up the PivotTable and all necessary PivotFields.
Detaile explanation of every step inide the code's comments.
Code
Option Explicit
Sub AutoPivot()
Dim Raw_data As Workbook
Dim PSheet As Worksheet
Dim DSheet As Worksheet
Dim PTable As PivotTable
Dim PCache As PivotCache
Dim PRange As Range

Dim Raw_Data_1 As String, Output As String, Start_Time As String
Start_Time = Time()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Raw_Data_1 = ThisWorkbook.Sheets(1).TextBox1.Text
Output = ThisWorkbook.Sheets(1).TextBox2.Text
' set the WorkBook object
Set Raw_data = Workbooks.Open(Raw_Data_1)
Set DSheet = Raw_data.Worksheets("Sheet1")
' first check if "Pivottable" sheet exits (from previous MACRO runs)
On Error Resume Next
Set PSheet = Raw_data.Sheets("Pivottable")
On Error GoTo 0
If PSheet Is Nothing Then '
Set PSheet = Raw_data.Sheets.Add(before:=Raw_data.ActiveSheet) ' create a new worksheet and assign the worksheet object
PSheet.Name = "Pivottable"
Else ' "Pivottable" already exists
' do nothing , or something else you might want
End If
With DSheet
LastRow = .Cells(.Rows.Count, 1).End(xlUp).Row
LastCol = .Cells(1, .Columns.Count).End(xlToLeft).Column
' set the Pivot-Cache Source Range with the values found for LastRow and LastCol
Set PRange = .Range("A1", .Cells(LastRow, LastCol))
End With
' set a new/updated Pivot Cache object
Set PCache = ActiveWorkbook.PivotCaches.Add(SourceType:=xlDatabase, SourceData:=PRange.Address(True, True, xlA1, xlExternal))
' add this line in case the Pivot table doesn't exit >> first time running this Macro
On Error Resume Next
Set PTable = PSheet.PivotTables("PRIMEPivotTable") ' check if "PRIMEPivotTable" Pivot-Table already created (in past runs of this Macro)
On Error GoTo 0
If PTable Is Nothing Then ' Pivot-Table still doesn't exist, need to create it
' create a new Pivot-Table in "Pivottable" sheet
Set PTable = PSheet.PivotTables.Add(PivotCache:=PCache, TableDestination:=PSheet.Range("A1"), TableName:="PRIMEPivotTable")
With PTable
' add the row fields
