Abort update immediatly... How?

i am setting an error message and ABORT = 1 in the start routine of the update rules... My logic is such that this error is always set during the first datapacket... If I do that, I want the process to be terminated immediatly whithout processing the remaining datapackets at all... right now, it sets the error message, turns the request red, but still all the datapackets gets processed unnecessarily.

if i have lets say 5 million records, and request is set to red in the first datapacket, there is no reason to process all the data, unless u have excess system resources....

any clue on how to terminate it immediatly after first datapacket?

Thanks
