This example creates a list of the cube field names for all the hierarchy fields in the first OLAP-based PivotTable report on Sheet1.
Set objNewSheet = Worksheets.Add
objNewSheet.Activate
intRow = 1
For Each objPF in _
Worksheets("Sheet1").PivotTables(1).PivotFields
If objPF.CubeField.CubeFieldType = xlHierarchy Then
objNewSheet.Cells(intRow, 1).Value = objPF.Name
intRow = intRow + 1
End If
Next objPF
