Dynamic Text Labels are used primarily in custom report label objects and in the Headers/Footers tab.
Two dynamic text labels are supported with SQL Spreadsheets: filter and Cell of the print dialog box. Because SQL spreadsheet objects cannot be selected on Web Analysis documents as on standard OLAP spreadsheets, charts, and pinboard, filter and cell functions must use fixed references to their data source. For example, the filter function must contain ReportSQLDataSrc, which is selected when a SQL subscription control is defined:
<<filter ReportSQLDataSrc1, 0>
A reference without a data-source specification (for example, <<filter 0>>) does not function with SQL spreadsheets.
