ASCP - Is it possible to purge plan data from a stored procedure ?

We are using Advanced Supply Chain Planning v12.1

We have a request from our business users to automatically create a backup of the daily plan  - before generating a new one - in the case of plan failure. The generation of the daily plan is done via stored procedure (launching the concurrent request during off-hours) and the backup would need to be automatcally created before the launching of the new plan. My thoughts are to purge the backup plan, initiate a copy to the backup plan and then launch the new daily plan. 

I certainly know how to purge the plan using the ASCP screen but am unsure if this functionality is possible to initiate via a stored procedure.  Is it possible to do?  Thanks in advance.
