How to: Extensions: Extend ssrs report - add second temporary table

The normal step is to use the process report method in the RDP class to populate the tables

but how do we modify this via an extension class.....

1. Create the extension class
2. Declare public variable for table to be added as new datasource for your report.
3. Create a method to return the additional table content - decorated with SSRSReportDataSetAttribute as per normal.
4. Create a public method to populate this table. - i.e. do what you would normally do in the process report method.
