Hi, Due to salesforce Limitation, you can't call a future method from inside a batch job and if you have a DML statement inside execute() method which triggers a call to future method it won't work because every run/instance of execute() method is a single transaction and so the trigger execution will be part of that single transaction. While @Future cannot be called from a batch class, a webservice can. A webservice can also call an @future method. So have your batch class call an apex webservice that in turn calls your @future method. There is one trick here. To call your webservice from the batch class, you need a session Id.

And lo and behold this works: 16 Mar 2018 Salesforce provides different options to run asynchronous jobs – Future methods, Batch Apex, Apex Scheduler etc. Future Methods: Future  Yes, we can't call future method from batch class.

In Winter '13, batch jobs can be chained by calling another batch job from the finish method of the current job. In other words, we can call a 2nd async method from a 1st async method, so why not allow it form @future methods as well? To take

This course teaches Salesforce's techniques of future methods, queueable Jobs, scheduled Apex, and batch Apex.

No, We cannot call future methods directly from batch apex but we can call a web service from batch class and that web service can call the @future method. Also, we can call the future method from finish method in the batch class.

A future method runs in the background, asynchronously. You can call a future method for executing long-running operations, such as callouts to external Web services or any operation you’d like to run in its own thread, on its own time. Yes, we can’t call future method from batch class. Some restriction of the future method are: 2) You cannot call another future method from a future method. As per Salesforce documentation, You cannot call a method annotated with future from a method that also has the future annotation. Nor can you call a trigger from an annotated method that calls another annotated method. If you do not have dependency between f1 & f2, you can call In Winter '13, batch jobs can be chained by calling another batch job from the finish method of the current job. In other words, we can call a 2nd async method from a 1st async method, so why not allow it form @future methods as well? To take Salesforce Developer Network: Salesforce1 Developer Resources. The maximum number of future method invocations per a 24-hour period is 250,000 or the number of user licenses in your organization multiplied by 200, whichever is greater. This limit is for your entire org and is shared with all asynchronous Apex: Batch Apex, Queueable Apex, scheduled Apex, and future methods.

Salesforce doesn’t allow a future method to be called from another future method or a batch job. While @Future cannot be called from a batch class, a webservice can. A webservice can also call an @future method. So have your batch class call an apex webservice that in turn calls your @future Allow Batch execute methods to be called from @future async apex methods. Opportunities & Quotes. In Winter '13, batch jobs can be chained by calling another batch job from the finish method of the current job. As I mentioned in your other question Execution Confusion in Batch class Apex, the ability to chain batch jobs together from the finish method was introduced in Winter 13. Winter 13 corresponds to API version 26.0, so your batch class will need to use that or higher to use chaining. Best Practices Ensure that future methods execute as fast as possible. If using Web service callouts, try to bundle all callouts together from the same future method, Conduct thorough testing at scale. Test that a trigger enqueuing the @future calls is able Consider using Batch Apex instead ++ All future methods and Batch Classes are Asynchronous and we can not call an Asynchronous call from and Asynchronous call. But to Take control of your asynchronous Apex processes by using the Queueable interface. This interface enables you to add jobs to the queue and monitor them, The reason why Salesforce objects cannot be passed as arguments to future methods is that the object can change between the time you call the method and the time it actually executes.Because future methods are executed when system resources become available. Future Method syntax: Future methods must be static and can only return void type.
