I am creating a batch class that queries on a call object and filters all the latest call records to populate this information on a custom object. My call records satisfying query is 6000 records so what happens is that the call records are divided across 3 batches and creates 3 records whereas I want this combined in single record. I tried to implement stateful method and insert in finish method. But this does not help,please help on this!
