hello,
even we were stuck with it. the reports were bursting out properly but we did not had a way to know as to which were succesfull and which were not. there is an option of "IsBursting()" function, but that wasn't helpfull either because it can be used only inside the report as a layout expression. but this function will tell you if the report is bursted to the reciepient or not. since it can be only used in the report layout, we can know if the report is bursted or not but, it can be only known if you open up the bursted report, which is not that helpfull. we had a case filed at the support for this enhancement. SDK probably has some extra functionality. you can ask the support if this can be acheived thru SDK.
Regards,
Skylab
