Excel – Tool to automatically combine many large pivot table in many large Excel sheet

Not extremely straightforward. I've rebuilt code from a daily dose of excel to take advantage of the better filtering options of excel 2010. If you select a data point in your pivot and run the macro, it will give you the matching lines in your source data. It does so by using the Show Details function, then creating a filter for each column to match the data.

You can set it on a new right-click button, or overwrite the default show details behavior.

Private mPivotTable As PivotTable

Sub GetDetailsOnSource()

'turn off updates to speed up code execution
With Application
    .ScreenUpdating = False
    .EnableEvents = False
    .Calculation = xlCalculationManual
End With

    On Error Resume Next
        Set mPivotTable = Selection.PivotTable
    On Error GoTo 0


   If Not mPivotTable Is Nothing Then
        If mPivotTable.PivotCache.SourceType <> xlDatabase Or _
            Intersect(Selection, mPivotTable.DataBodyRange) Is Nothing Then

            Set mPivotTable = Nothing
        End If
    End If

   Selection.ShowDetail = True
   GetDetailInfo

With Application
    .ScreenUpdating = True
    .EnableEvents = True
    .Calculation = xlCalculationAutomatic
End With

End Sub

                    bNumbers = True
                    rCell.EntireColumn.NumberFormat = "0"
                    rCell.EntireColumn.TextToColumns Destination:=rCell, DataType:=xlFixedWidth, _

The Pivot Table will always pull the unfiltered data for its source.

You can cheat a bit by creating a Table from your Source sheet. Then as you add columns to your Pivot, they should bring the Table filtering that you've already done with them.

Also, you can then filter the data directly in the Pivot Table. Depending upon your data source, you could pre-filter the data before it gets to Excel. I do this fequently using SQL as a data source and writing a view that pre-filters data before importing.
