Does XLSIO have classes that map to the PivotTable.PivotCache.MissingItemsLimit property.
I'm trying to mirror the following VB script to resolve an interesting data refresh problem...
Sub DeleteMissingItems2002All()
'prevents unused items in non-OLAP PivotTables
'in Excel 2002 and later versions
'If unused items already exist,
'run this macro then refresh the table
Dim pt As PivotTable
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
For Each pt In ws.PivotTables
pt.PivotCache.MissingItemsLimit = xlMissingItemsNone
pt.PivotCache.Refresh
Next pt
Next ws
End Sub
