In previous versions of BusinessObjects (6.5 and prior) application developers had the ability to purge saved data from Webi documents.

With the move to the Enterprise backend this functionality was not migrated over.

BusinessObjects Enterprise XI 3.1 has added this functionality back into the Java REBean SDK.  You can now purge saved data from a Webi template as well as reset the prompt values that were used during the last refresh of the report.
