Call future from future salesforce

You cannot call a future method from another future method as both them are asynchronous. In salesforce you cannot call one asynchronous function into another asynchronous method. As per the salesforce documentation:-You cannot call a method annotated with future from a method that also has the future annotation.

A future call allows Apex code to kick off some other Apex code that will run later, and then the current transaction can continue without waiting for that other code to complete. One worry when trying to do future calls is that there is a limit to the number of future calls based on your number of licenses or an org minimum of 250,000. When you specify future, the method executes when Salesforce has available resources. For example, you can use the future annotation when making an asynchronous Web service callout to an external service. Without the annotation, the Web service callout is made from the same thread that is executing the Apex code, 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: You cannot call a future method from another future method as both them are asynchronous. In salesforce you cannot call one asynchronous function into another asynchronous method. As per the salesforce documentation:-You cannot call a method annotated with future from a method that also has the future annotation. Yes, future method can be invoked from Trigger. Many examples: https://salesforce.stackexchange.com/questions/173444/help-with-calling-future-method-from-trigger

Using @future annotations, your method execute the callout when your salesforce has resources available.You can call future method for long operations such as web services because future method runs in background asynchronously.Use the future annotations when making a asynchronous callouts to the external service.

You cannot normally call a future method in another future method, but if your salesforce license has the pilot feature enabled then you can call a future method from another future method. To get the pilot feature you ll need to contact the salesforce where you can also double or triple some governor limits of asynchronous apex in your org. 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 both methods one by one from original class. Future methods can’t be used in Visualforce controllers in getMethodName(), setMethodName(), nor in the constructor. You can’t call a future method from a future method. Nor can you invoke a trigger that calls a future method while running a future method. The reason why sObjects can’t be passed as arguments to future methods is because the sObject might change between the time you call the method and the time it executes. In this case, the future method will get the old sObject values and might overwrite them. A future call allows Apex code to kick off some other Apex code that will run later, and then the current transaction can continue without waiting for that other code to complete.

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.

To get the pilot feature you ll need to contact the salesforce where you can also double or triple some governor limits of asynchronous apex in your org. 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. Don't call Userinfo.getsessionid from a scheduled batch class. You won't get a result. Instead, call Userinfo.getsessionId from your scheduleable class and pass the id into your batch class as a parameter. In salesforce you cannot call one asynchronous function into another asynchronous method. As per the 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. ++ 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, Future methods can’t be used in Visualforce controllers in getMethodName(), setMethodName(), nor in the constructor. You can’t call a future method from a future method. Nor can you invoke a trigger that calls a future method while running a future method.
