BIRT tips

Two useful tricks are used in this BIRT exercise

Use of the <beforeOpen> event handler for the data set to manipulate the query WHERE clause

Use of a ‘dummy’ required variable so that BIRT will pause and present the user with the parameter selection dialog.

Otherwise it continues into the retrieval of the data set
