尝试同步切片器：运行时错误438

Question

尝试同步来自两个不同数据源的两个切片器。我将使用第一个切片器来更改多个图表的视图。来自不同数据源的字段是相同的，其中的值相同。我是VBA的新手，所以只需学习一下。

Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)

    'Declaring variables
    Dim sc1 As SlicerCache
    Dim sc2 As SlicerCache
    Dim SI1 As SlicerItem

    'These names come from Slicer Settings dialog box
    Set sc1 = ThisWorkbook.SlicerCaches("Slicer_Customer_Region1")
    Set sc2 = ThisWorkbook.SlicerCaches("Slicer_Customer_Region2")

    'make the macro faster
    Application.EnableEvents = False
    Application.ScreenUpdating = False

    'Clearing filters to mirror sc1
    sc2.ClearManualFilter

    'Getting error here
    For Each SI1 In sc1.SlicerItems
    sc2.SlicerItems(SI1.Customer_Region).Selected = SI1.Selected 
    Next SI1

    'make the macro faster
    Application.EnableEvents = True
    Application.ScreenUpdating = True

End Sub
