Workbook Email Scheduler is only available in cloud edition of Oracle Analytics (OAC).
This feature is (along with export to Excel, which is so badly implemented in OAS, that is makes it very hard to use) highly requested by our "business" user.
Since it balances the differences compared to classics tools in OAC/OAS (Delivers component).
So I am asking Product Mgmt/Development to evaluate inclusion (but seamless inclusion, not like for DV Export to Excel functionality) of Workbook Email Scheduler into future release of on-premise version of Oracle Analytics (OAS).
