SFDC ROCK one batch apex to another batch apex
we can not call one asynchronous process to another asynchronous process but how can we call from one batch to another batch since batch is also asynchronous process?
Greetings to you!
There's no rule that says that "asynchronous cannot call asynchronous". There are specific rules in place, such as "future cannot call future". A Queueable can call another Queueable, a Batchable can call another Batchable in the finish method, and Scheduleable methods can call Batchable and Queueable methods. There are usually lesser limits allowed for asynchronous contexts (e.g. a Queueable can call only one Queueable, while a normal synchronous transaction can call 50 of them).

To call another batch class from a batch class:
1. Call another batch class in the finish method as execute method is called many times but Start and finish method only once.
2. So once your main batch is completed and the finish method is called and then it will call another batch.
