18.10.1.7 cacheSource (PivotCache Source Description)

Represents the description of data source whose data is stored in the pivot cache. The data source refers to the underlying rows or database records that provide the data for a PivotTable. You can create a PivotTable report from a SpreadsheetML table, an external database (including OLAP cubes), multiple SpreadsheetML worksheets, or another PivotTable.

DocumentFormat.OpenXml.Spreadsheet.CacheSource-ima

Information about the data source is stored in the connection element and is retrieved using the connectionId attribute.

[Example:

<cacheSource type="external" connectionId="1"/>

end example]

OLAP data sources are distinguished from other data sources in SpreadsheetML. OLAP records are not stored in the pivotCacheRecords part, whereas all records for non-OLAP data sources are stored in the cache.
