[Name] SourceType [Required/Optional] Optional [Data Type] Variant [Description] 
An XlPivotTableSourceType value that represents the source of the report data. If you specify this argument, you must also specify SourceData. If SourceType and SourceData are omitted, Microsoft Excel assumes that the source type is xlDatabase, and the source data comes from the named range "Database." If this named range doesn’t exist, Microsoft Excel uses the current region if the current selection is in a range of more than 10 cells that contain data. If this isn’t true, this method will fail.
