IWR report generation process on demand v/s bursting

[Rajey]

Is it is possible to maintain two ways of report generation at one point of time and if that is not the case how complex it is to switch between the two report generation process ( bursting and on demand) for any reports that are made avaliable to upfront ?

if some one can inform the level of effort that is required for a admin to switch between on demand report generation to bursting the reports and vice versa that will be great !

Thanks
