Hi, Virtual DataPort provides an API to develop custom stored procedures written in Java. For your scenario, I would write a custom stored procedure that executes the steps mentioned in the below order and import them as base view in Virtual DataPort. * Pre-Processing steps. * On success of 1# , Steps to retrieve the data from source. * On success of 2#, Post-Processing steps. Thus, when this base view is executed, the above mentioned 3 steps are executed implicitly by the stored procedure. The [Developing Stored Procedure](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/developing_extensions/developing_stored_procedures/developing_stored_procedures#developing-stored-procedures) User Manual of the Virtual DataPort Developer guide explains this in detail. Hope this helps!
